Hey, I have owned a 1991 vette for about 9 years. It has 120k miles and has been a daily driver. I have recently experienced a rough idle, which smooths out under excelleration, but then surges. Any suggestions???

I've got absolutely no experience with C4 but at 120 clicks there are several things the happen to more than just Vettes. Some thing to consoder are: dirty injectors, burned out plug(s), cracked plug wires, burnt valve(s), timing off. We'll get someone around here htat is smarter than me.

And WELCOME to DC
