alright when I am idleing at a stop light or stop sign something for a little while. the tach will go down to 500 then back up to 1000 then slowly all the way down to zero. then it sounds like the engine restarts it self then is fine for a little while. whats kausing this to happen??? I just replaced the drive belt and all the plug boots and wires so that isnt the problem. any one else had this happen???


The picture attached is a piece that i found laying down in a crack on the engine when i was working on it, anyone know what it is or where it is supposed to go? it was laying under the TB.

Idle problem either the Idle Air Control and\or the upper intake gaskets (2 for the V6)

Take the IAC off and clean it! Two 7mm bolts and its off!

As for the picture of that thing you found under your throttle body... I have no idea! It could have been part of some of the vaccum tubing under there. The lower half of the image is pretty blurry.

P.S. Dude! How rude of me! Welcome to the group and hope you enjoy!

2 part dumb question: do the atx tours have one? where is it? i dont think i've seen it in the haynes manual

yes, it's in the manual. not sure exactly where it is, but i heard it's hard to get to, atleast on zetecs.

Do you have the TH hang fix installed? I had the EXACT same problem with mine, and I tryed cleaning all the intake parts, tested everything while there, even used the smoke machine to fill the intake with smoke to check for vacuum leaks. Nothing. Then I took out the throttle hang fix, and whah lah! It runs perfectly now. Mine's a '95 as well

PS- while your in there..

Carefully take out the MAF element (using the special screwdriver), and clean the little elements sticking out of the unit, using brake and parts cleaner (just spray it down til the elements don't have any black carbon on them anymore). Guaranteed to make car run better (if it had deposits prior, which it probably does). I've fixed several FORD drivability complaints at work by just doing this one thing alone

They all have an IAC. Perhaps you have a Zetec in which case it's under the intake manifold and hard to see.

I found one of those little black "cap" things -whatever it is.. lying between runners of my UIM! (2.5 ATX) Have no idea what it is or is supposed to do either. Currently in the change tray of my dash -waiting for somebody to identify it. Car runs great with/out it attached to anything. Couldn't fin any reference in Haynes either. Maybe part of ABS/TCC? -I've had CEL's on that. As for your idle problem.. Take off the TB and check that the EGR ports are clear - mine were plugged with black crud and had similar prob. Clean-out with solvent and air and works fine now.

"Take off the TB and check that the EGR ports are clear - mine were plugged with black crud and had similar prob. Clean-out with solvent and air and works fine now. "

I took off the tb and tried to clean as much black [censored] off as i could but right inside the intake head thing. there are some litle pokey things sticking up, are those the things your saying to clean. btw: what is the EGR ports. Sorry i dont have the contour lingo down yet. I know just about everything there is to knwo about grand am's but the contours' engine is quite new to me. thanks every one for your help so far. the throttle hang problem is that when the gas peddle sticks while driving, and where can i find the fix to this, i tried putting a little rubber door stop on the adjustment screw and that helped but it isnt permanient. thanks

The little pokey things sticking up are just diffusers. Make sure the gasket is off and there is a channel in the face that needs to be cleaned out.

EGR (exhaust gas recirculation) ports are just the passages that let the gasses back into the intake.

Use carb cleaner on the throttle body but don't get it in the plastic throttle position sensor. Get the gunk out of the bore and off of the flap.

Make sure the external return spring is on there.

Some years had stickey cables, if it keeps up you may have to replace it.

my car is doing the same thing.... where is this IAC valve on my car thanks.

The IAC is the silver tube like thing that is attached to the back of the upper manifold on the driver's side. The air bypass hose comes in right by it. Two 7mm bolts and it is off!

I cleaned mine and reattached it two years ago and have had no problems with it.

-Lance

how do ya clean it just blow it out with a compressor ?

do you have to replace the gasket if there is one? I haven't had time to pop the hood yet..... in NY we still have like 6 inches of snow on the ground. thanks

No, carb cleaner, no force.
Gasket is your call. If too much of the graphite chuncks off it's a good idea, same for throttle body.

I believe this is the part that you are talking about, its in the middle back by your winshield, It as a pain in the ass to get to, I removed it and cleaned it and the gasket broke so I ended up making my own. The hole thing only took about 15-20 minutes to do.

If you can't find it look at this picture and see if it helps
