Question about 2006 Chevrolet Cobalt

1 Answer

High Idle Issue

Recently I replaced my MAP sensor and cleaned my throttle body in an attempt to fix a low idle issue. That problem has been fixed, but now instead of idling at 700-900 rpms like usual it idles at 1500 rpms. No amount of disconnecting the battery and driving it has relearned the rpms. Currently I am waiting for my shop to get the right CAN connector for the scanner I need. My question is, has anyone else come across this problem? If so, what was the solution? Also, has anyone had a problem with the throttle body or the throttle position sensor going bad? Any help would be greatly appreciated.

Sounds like the idle speed control motor is stuck, this could have been caused by the cleaning.

2002 Buick Rendezvous CXL will idle very high & idle too low & stall when going slow or stopping.Replaced IAC valve. Service engine soon light not on, but service vehicle soon light always comes on.


Check for applicable trouble codes. Some of the national brand auto stores will check codes for free.

You may need to clean the throttle body and clean those small passages. With a high idle block off mouth of throttle body, should have a big effect on the idle? There are several issues that could cause idle to act up. Vacuum leak--maf and or map sensor. Don't replace anything unless testing points you in that direction.

Idole to high


If your idle is too high it can mean a few things with computer controlled engines. Most common problems relate to the sensors in your throttle body being dirty or faulty. If after your disassemble your throttle body and clean the throttle body and sensors you still have the issue you can adjust your idle through the Idle Adjustment Screw.

2003 toyota sienna idle problem


After about 100K + miles the idle air control valve (IAC) begins to collect carbon deposits that interfere with the movement of the spring-loaded valve. You will not be able to clean this without removal and dissembly of the IAC body. Use an emory cloth or fine sandpaper to remove the build up around the valve. This should free it up to rotate without binding. This is a temporary fix, of course, and will either require cleaning again or replacement of the valve. Getting to the IAC requires removal of most of the intake upto, but not including, the intake manifold. Total time is approximately 3-4 hours, but worth it. Good luck, and I hope this helps.
