I was driving home today and the CEL came on. The car began to idle at 2000 rpms, while I was sitting in traffic. I was trying to get it to come down, so I began to release the clutch pedal and it the idle would drop down and almost die. I had to give it gas quickly to keep it alive. So the rest of the way home it continued to idle at/around 2000 rpms. When I pulled in the driveway and shut off the car, I tried to get the CEL to blink so that I could count the lights. It would not show me.

I either think it could be the Idle Air Control valve or Throttle Position Sensor, both of which are somewhat costly. I will not be able to take it somewhere until Saturday to get the CEL read. Let me know what you guys/gals think.

Thanks
 
Well, the light went off before I was able to get it checked, but it came on again last night and is still on this morning. I am hoping that it will stay on so that I am able to get it checked. I will let you know. Thanks
 
I would test the resistance across the pins on the iac solenoid. The pins are numbered 1-4 from left to right and the resistance acoss 1&4 should be 35-52 ohms and the resistance across pins 2&3 should be 28-52 ohms. Hope this helps.
 
mine was doin the same thing.......i replaced the tps sensor iac motor and the map sensor........it was still doin the same thing

so i took it to a shop and they said my intake manifold gasket was bad and it was drawing air into iy makin the idle surge
