92 Laser RS Turbo AWD engine light problem..

[Laser06]

My check engine light is coming on and the idle is bobbing from 700 RPM's to about 1300 RPM's. Something is wrong, I was told a sensor, any other ideas of what it could be?

Have the codes checked..... Dave

buy a datalogger and use it to check the codes, the datalogger is one of the best tools to have around with dsm's. if you ever plan to mod your car, this will be a must

Try to get access of a code reader if you can, it will tell you what sensor is failing or has already gone bad.
