I put this I put this under exhaust because I'm not sure but I change my EGR and my map which I replaced back to the older map and the ponytail is bad could that cause the problem I don't know it shakes and it may be the exhaust I'm not sure anybody got a heads up on that thank you

A couple of questions first to determine were the problem is coming from.
1 Did it all of the sudden start shaking or over time.
2 Does it shake when having the van parked and engine idling.
3 Does the van shake when driving it.
4 If it is the motor, can you see it shaking when the hood is open..
Answers to these might help other people ask more question to determine your van's problem.

If it shakes during driving , do you feel the steering wheel move back and forth.?
Does shake more or less or no change when pushing the brake pedal when slowing down?
Is there any grinding noises when it shakes while driving?
Does increase the shaking the faster you go?

Thank you for the replys, over time it has been shaking, it's much sooner now, no the engine doesn't shake, it sounds and drives smooth though every now and then I might feel a miss but unsure.no only when driving it doesn't shake when in park, and yes at around 55- 60 mph it shakes,that's when it first started back when. Now it's like 20-30 mph it shaking,the steering wheel shakes.
Does it sound like an alignment needs to be done? Where I'm at it's iffie mechanics if you get my drift. Back in the day an alignment was 20 bucks,now they want 120 to 150 bucks for an alignment. And my gas milage seems to be tanking.

There a bunch of things that can be wrong but I will suggest you look at 2-3 items first.
It can be your tires are damaged inside or maybe the rim.
It happens when you hit something hard with the tire, like curb or big pot hole.
If you have some spare tires you can swap them or if only one then do one at a time.
You can do that your self, just tedious and will tire you out a bit.
A garage can check that out too.
The next thing it can be is the universal joints on your drive shaft.
There are two on a RWD Van after the transmission to the rear differential.
More on All Wheel Drive in the front but those mostly just go for the ride till they need to do something.
Even though the front half-shafts spin all the time as the front wheels turn.
Usually the front AWD wheel bearings go first that's besides the point.

I hope this helps you find the problem . Other people may have other ideas.
There is someone else down the question list that has a engine shaking but that seams to be a motor problem.
