And so it begins, my '93

The white wench and Philomena, my '97 meets my new to me '93.


She goes by the nick Phil my bride gave her because of the escapade my son and I went through to bring her home. My oldest works for a towing company so he got me a deal on a flatbed to go get the '93. $500 for the truck and fuel out to Lancaster PA and back to Danbury CT. Seeing as it was going to be a daytime run he got the new truck not generally used unless they are overwhelmed with calls or they want to make a showing like at the Porsche dealership. A few weeks ago they got new GPS systems, fancy stuff that deals with dispatch and call management, which is cool, but this one had not been set-up for the truck yet and all the avoidances were set for default values. Toll roads, parkways, underpasses less than 14',,,, we found ourselves driving through downtown Philadelphia. Not fun on potholed one-way streets that were originally built for the width of two horses butts. That's how she came to be known as Phil.


Phil is now registered, passed emissions w/ a new gas cap. I did an oil change and air filter beforehand. The truck sat more than drove, does the puff of smoke at startup and the oil smelled like fuel. I used a qt. of Lucas, a stop leak they sell for oil, a qt. of Duralube and topped off w/ 5w30.
The trans needed fluid, topped that with the Lucas trans medic stuff till I can get to a proper flush and filter.
CT doesn't do a safety inspection any more but I changed the wipers, found the washer hose needs repair and the headlights need to be aligned. All the other lights are working and the rubber is good.

Lots of little things need be done. The FSM came in today all I need now is the weather to co-operate and a little time to get started.
A full tune up, plugs, wires, cap and rotor. I'm a little up in the air as to whether I'll try any aftermarket performance parts like the MSD ignition or not but the bare minimum will be AC Delco.
The stereo is relatively new but needs to be wired properly. (Confused speakers)
The steering is a touch loose. I'll give the box an adjustment and see what happens, having a spare van it won't be a big deal if it goes south and I need to wait for parts.
The steering column is loose, the four bolts at the bottom of the tilt and the part the gearshift rotates with are flaky., not bad but they won't improve on their own. I've been in there on an S10 so I'll manage. I've got a new 14" 3 spoke wheel to go on so that can't wait.
The oil cooler lines leak so those need replacement.

Hey CM, I'm hoping you would be so kind as to post up info for HPTuners, which software, where to find the cable any notes you may have made sure would be helpful.
In the hotrodding the 4.3 thread someone posted a riser for the throttle body and a "shim" for the jets, any idea where to find these goodies?

I think the EGR is sticking because the SES come on on the highway and shuts off at restart I'll try blocking the EGR on this one and see if it throws a code. If it does I'll do like my '97, clean screen and any other goodies that run to the intake get capped at the intake and vented down and out.
With luck I'll be able to afford paint this year, we'll see what the summer brings. Things like the visors are old and stiff to move, bits of interior that need attention but it's all there plus a little more that Scott picked up and gave me in the deal, to say the least I'm very happy with the deal we made. Scott was aces and I hope the cash makes parting with this gem a little easier.
I'm sure I'll find more as she's an old girl but she's mine.

Did I mention cup holders??? They stink but I have some ideas,,,, Stay tuned.

Timing adjustment and TBI spacer are going to be your cheapest easiest power gains. Here is where mine is at. Take the doghouse off and brake torque it and adjust to where it runs the best. Then drive it a little. If it goes into limp home mode just back it off a hair.

Thanks Randy, I appreciate all. The timing adjustment you speak of is just the dizzy clamp, no?

Raz, the cup holder is simple. I saw one here for the gen 1 van not too long ago. I'll use piece of 3/4" oak cut to fit the profile of the stock shelf, holes drilled where the cup holders are now with a tray cut-out in the center. All very similar to what is there now.
Can't say what if anything I'll do for a console, I'm going to run without for awhile and see how it goes.

No! No more driving through the tunnel while they check stuff? That's no fun...

She looks nice in the driveway. Don't let the white van get jealous, though.

What code ware you seeing?
 
#8 ·
Yea just the dizzy clamp. Night and day difference there.

If your going to use the stock cup holders. Just save time and throw your drink upside down on the floor. Usually ends up on the mat and in the footwell. Floor consoles are where it at. I got the Big Bubba coffee cup. I can do anything it hasn't spilled yet.

Nice ride Scott, Detroit is trying, the camaro and mustang both have caught my attention, I wonder if they won't at some point in time replicate the astro,,,

Leann, CT gave up the saftey a long time ago, they still make you get a temporary plate, take the emissions and pass or fail you go back for the hard plate, if you fail the emmisions you have 60 days to make repairs and retest. :shrug: Why bother with the temp?

No code, I haven't had the chance to try to read it. I'll need to learn how yet. Got a link somewhere?

I wonder what the imagineers were thinking when they designed those cupholders anyway? wait a minute,,, first astro came out in '85 right? let's see, 4 or more years college, puts them about my age,,, we had some good weed back then.
 
#11 ·
Thanks Leeann,
I was searching as your post popped up, I found several old links some good some not so, but I found this linked in a thread, so I copied and paste here if anyone searches they'll find all the info in one place, not just a broken link. It jives with the one you gave plus has the definitions.

http://www.cfm-tech.com/gm_tbi_trouble_codes.htm


OBD1, jumping the ALDL to read code.

With the engine off and the ignition key turned to the 'Run' position insert a paper clip or small jumper wire into terminal's A and B - the top two furthest to the right.

The check engine light will start to blink. The first code will be 12 - one flash of the check engine light followed by a short pause and then two quicker flashes of the check engine light. How do we know you'll have this code? All vehicle's with a working Check Engine Light will have this code! It is a diagnostic test to make sure the light is working. If there is no blinking light - the light does not work.

All codes will be shown 3 times in a row before the next code (if there are any) will appear. How do you know when all the codes have been shown? Code 12 will be shown again. The codes will keep cycling until the "jumper" is removed from the A+B terminals.

If you have not retrieved codes this way before do not become embarrassed if the flashing Check Engine Light leaves you a little mixed up - it's kind of like Morse Code but in a much easier way. If you get confused you can re-start the whole process by removing and then re-installing the jumper. You'll catch on within a few minutes of doing this.

3) What do the codes stand for?

I'm certain phil has posi or limited slip but the compnine does not show G80. When I put her on ramps for the oil change I thought it odd there were 2 ruts from the rears in my gravel drive. Today leaving the house on the road I laid into the gas and left 2 long ruts behind. (dirt road) Still not quite beleiving my good fortune a little later I hit it on dry pavement. Yup, two strips. On the asphalt I could hear both tires grabbing so tell me did I miss somethine on the compnine sheet? What are the codes that I would look for in the glovebox?
Here is the compnine.

I didn't see the Posi in your code, but it's a 20 year old van, who knows what a PO could have done. Or like CM's van, the factory could have slipped it in there w/o marking it down. But if you do have it, score!

-Andrew
 
#15 ·
Yes, it does have the fiberglass springs and both front and rear seem very fresh, I don't think the van has ever really been loaded or ridden hard. As for the wheel hop there still is a dusting of sand on the roads from the snow last week, not so much to see but if you you're on a bike you'll know it's there!
Scott said he bought it in '98 and kept up on the maintance. The last few years he put very little mileage on it yet those wheels have zero rust on them. He kept it parked outside and we all have seen what happens to chrome wheels if you don't wipe them weekly.
I didn't think I missed anything when I read that list but what do I know? I was thinking there may be a different number in the RPO codes in the glove box, something other than G80? :shrug: is "RPO" the right term?
I dunno, another item on the mystery list. I'll have the differential open this summer to change the oil so I'll find out for sure then.

I may be forced to as the site I used seems to be down. For years I used a small site with no advertisment supported by donation. Could be his pickings got slim and walked away. I sent him an email out of curiosity but I expect he's closed up shop.
 
#20 ·
Woodbutcher. You ask for all my dirty little performance secrets.
I forgot one in that list and probably others to.

But biggie just dawned on me seeing and reading your thread.

Handling.

The way the door handles rub the ground on corners. Pogo stick like ride. And the way you have to stop and turn the turn signals on in the corners.

Some negative camber. Mine will flip if you ain't carefull with the big tires. No more turn signals needed.

I used gas shocks for the pogo stick thing.

Air shocks with dual lines. It now tracks flat in corners.

Between those 3 things it rides better still no sports car. But at least as well as a Impala.

:auto-layrubber:
 
#21 ·
Thanks CM, I've seen your posts mention the camber. I do my own alignments too, I've had to because of the overload I run in my work vans. Back in the eighties I knew a guy that showed me the ins and outs. Even though his best works only turned left he knew his stuff. If my '97 is set-up by the machine to factory spec I get the "death wobble" braking at highway speed. Camber will help that a little but if you go the opposite of factory spec on caster, to a toe out the problem is solved. You get a slight scrubbing wear but if you don't go to far your golden.
The '93 needs the steering tightened and must have the smaller wheel. I feel like I'm driving a huge truck when parking. If the time comes to replace the steering box I'll look for the faster gear.
Shocks seem good for now, couple years on gas shocks. I have a pair of the monroe heavy duty gas shocks for the rear I had to put on the '97 while waiting for my replacement Ranchos, They were too soft for the work truck but may be ok in the '93.
 
#22 ·
Finally,

wait for it,,,

Cupholders! :clap:


Real simple, put a couple holes on 3/4" oak, w/ a strip of velcro on the back edge so it comes out easy for cleaning. I'll find or make a catch all tray for the center and that issue is fixed.
 
#25 ·
I really hated that stock wheel. When I got the '97 the rubber had separated from the steel core at the 12 o'clock. I changed it to one of these ten years ago and love the smaller size. With power steering we just don't need the bus drivers wheel.

Working on the sound system,,,

viewtopic.php?f=32&t=23289

I think I've decided on the paint. When I gave her a bath I liked the way the old colors (faded spots) looked. I'm thinking I want to repair the surface rust that is in the black around the windows only and repaint that black but the rest simply wet sand and re-clear.
When it was wet I got a preview, the places where the clear coat is gone have faded a bit and looks cool. Kind of like my jeans, a little thin in the seat and knees but boy they just fit good. I'm thinking to peel the trim and re-dye it all black, paint the grill satin black, but keep the worn paint. I'll find a touch up to fix the chips, the few little dings can stay. This way when I do find scratches the will be easy to hide, she's not perfect and it would drive me nuts to try to keep her that way.
This weekend I'll go to a body shop or two and see what they have to say about a new clear coat on top.
