Default 1996 LT4 Running Terribly

Hi guys,

I have a friend who has a 1996 LT4. The car runs great most of the time, but there are times when the car wouldn't perform too well. It's a daily driver.

Every now and then, it would be driven, stopped at a stop light, then the engine would start running at 1200RPM, sometimes reaching 1600RPM on idle. After a while, it would have a hard time accelerating, and the check engine light and ABS light and other lights on the dash would come on.

After that, the car is turned off, started again, and it would go back to normal driving operation. Any thoughts on this? I'm not too familiar with C4's myself, so any help would be appreciated.

Thanks

-Arvin

Scan for error codes to find out what is happening. Most auto parts stores will do this for free.
