A while ago i noticed my car idles somewhat rough, not very bad, small enough that a passenger can barely feel it when sitting at a light. But to me its feelin like the world is rockin and i could feel it a mile away. (that bond between man and his corvette :)) Anyways i have changed plugs and wires, and have run several bottles of fuel injector cleaner. (the wal-mart stuff) nothing has really worked yet. My car is a 02 with 70,000 miles. Any ideas or advice would be nice.:confused:

For your question, I use ZMAX in my C5 when it started idling rough and it WORKED!! Now it worked for me!! Try it and see if it works for you!! Here is there website www.zmax.com Tim c5garage
