Hello Mary Roussell,

IF the HIGH IDLE is a new condition (post gasket)

You need to look at all ends of the throttle cable
and make sure the CABLE SHEATH in FULLY
SEATED at the ends... Most likely the end that was
slack where you were working (but ALSO check
inside the firewall (top of the accelerator peddle).

HOWEVER... if the word "STILL"...
As in "STILL... idling to high"... was left out

You are looking at the NOTORIOUS GM
cold IDLE valve** issue... It is famous for making
FI cars with automatic trannys to STALL

at BBB Industries website (FREE, registration required).
((contains CRITICAL throttle specifications as well)).

** cold IDLE valve mimics the CHOKE function.

High idle on 86 Ford Bronco II (2.9L). Have replaced IAC, TPS and ECT. Also checked all vacuum lines. No fix. Need help.

I have heard of coolant sensors staying cold and keeping idle high but not a particular model.

What causes my 1993 grand prix to idle high on start up and keep climbing until the engine light comes on

Pontiac 6000 STE Idels Rough

Try cleaning the Idle Control Valve by removing the air cleaner duct work and buying carb cleaner and to the fuel side system there are two holes to the sides of the cylinder. Spray directly at these holes with the engine running at about 1200 rpms. Spray a good bit of it about 10 seconds. Then turn off the engine and let the cleaner soak. Repeat the process a few times. See if this works for you.
If not the idle position sensor may be bad. Get a trouble code at any Autozone or similar store for free.

Timing a pontiac 6000le 2.5 engine

first check to be sure the vavuum lines at the throttle body are in there correct places.
on the main pulley of your engine, the one on the crank shaft there will be a little notch on it. mark the notch with some chalk or a dab of white paint. then loosen the bolt that holds down the distributor until you can turn the distributor. turn the distributor a little bit, snug the bolt up and try it. once you have the car running you will need a timing lite to set the timing to the correct timing mark. which should be 8 degrees before top dead center for you car.

Car idles too high and dies

The later 80's accords have a problem with idling being to high at start up, even when the ambient air temp does not warrant it. I have had a 86 and now an 87 accord and both did that. I pretty much deal with it, being as you cant hardly replace indiv carb parts. Adjusting the idle will do nothing to stop it either. I took my 86 to a shop when I still had it and he fixed it, but I cant remember what all he did. I know he drilled a couple small holes in the choke plate. I think that the thermowax valve is bad, but again, you cannot find just a thermowax valve or anybody who knows what it is. Replacement carb in my area is about $450. Like I said, you might just have to learn to live with a high idle at start up.
