As , with most corsicas , around that time , it seems that there is a general problem with the cruise control . . .
try unhooking the arm that connects the cruise control to the engine . . . should be easy to take off ,
and see if that helps the problem

My van is idle high i cleaned the throttle boady and it idle down the a few hours later its high idle again why i replaced two sensor and still idle high


Hi Alexandra, Im AL the owner of Big As Auto Repair

There are several things that can cause high idle, but the 2 most common problems are as follows.

(1) You could have a vacuum leak somewhere on the engine. Here is how to check for that issue. Here's what I want you to do: Buy a can of CARB Cleaner and while the engine is running spray around the Intake Manifold, the manifold is the thing the throttle body sit on. Also spray around all the vacuum line as well. If while spraying there is a change in the idle speed then you have found your leak. If there is no change then move on to step 2.

(2) Sometimes when you have a high mileage vehicle parts begin to ware out or can also begin to stick in place. Here something you can check. Idle Air Control Motors can start sticking from corrosion build up and can cause a high idle issue. Here what I want you to do. Start the engine and let it idle, while its idling I want you to tap on the Idle Air Control Motor If it idles down to normal idle speed replace the motor. The motor mounts onto the throttle body and most of them are round. Once you replace it and start the engine you'll notice that its idling real high, :This Is Normal, just let it idle until the engine controller resets the idle speed to normal.

Hope this helps and should you need further help please visit my auto repair website. http://www.bigasautorepair.com/

92 chevy idles real fast on cold start up, then after run warming up runs fine


Not an uncommon issue for one to idle fast while cold but , 2000 rpms is a little higher than normal. May want to check the engine coolant temperature sensor for proper voltage and the coolant level. Also, check for small vacuum leaks around the throttle body gasket.

Ok i have a 92 chevy corsica and after it has been running awhile when i go to slow down to stop at a stop sign the car dies how do i fix it


well if it runs normal when your driving then it sounds like a gas problem or maybe you need to adjust your idle a little bit, other than that it could be fuel filter or carburetor adjustments
