Hi I have a 1992 Corvette that had been running just fine till the other day then it started running rough and has a lack of power. When idiling it is going up and down a lot it never did that before and when on the road it is like skipping and running rough.

I suggest starting by checking for codes. Do that and let me know if you find any. Also, check to make sure the catalytic converters are not plugging. You should also check fuel pump pressure and the idle air control valve which is responsible for maintaining a smooth idle.

If there is a code, it can save a lot of time.

Let me know.
