At first sorry for my English I am from Kiew, Ukraine. But I hope it will be no problems
I received GMC Safari from my grandfather. This car in our family from 1993.
car was 3 years on the parking and I started to reanimate it.
But first problem with High engine speed by idle.
I think it is something wrong with TPS or IAC sensor? It is possible, how can I check it? Where I can find IAC Sensor? It is possible to repair this both sensors?
I hope for your answers!
Till now I repaired only: MAP Sensor, breaks, problem with oil in transmission etc...
Thanks a lot Uncle Bob,
Unfortunately web-links which you wrote not found.
Do you have some video or photos haw I can do the cleaning by the throttle body? Or manual?
I will try to find another sensors in Kiev, but we have a big problem with parts for Americans cars (price, shipping, etc...)
Which one Injector cleaner you can recommend, for example?
I refuel with normal petrol (76-92 octane number/value by "Shell") and I test car on petrol, but I have LPG(Gas) too.
I think I found some Infos about cleaning:
and for TPS http://www.ehow.com/about_5645681_gm-th ... blems.html
Important is:
Maladjusted TPS
If GM TPS sensors have any inherent flaws, it is a tendency to slip out of adjustment. Though this can happen to any car, many GM owners have reported such a failure. The TPS must be adjusted (rotated) so that it reads idle and full-throttle positions properly, or it may appear to be malfunctioning. Try adjusting the TPS before replacement to save a few dollars.
I am on right way?
So, I'm in Kiev.
First problem was transmission:full rebuild, master kit etc...
Next problem was high engine speed by idle. I order the rebuild kit for TBI from USA and timing chain- hope TBI rebuild will help me in this case.
What can I do more?
thenks, will check all leaks and MAP sensor next weeck.
