Rough Idle
Just joined the forum today. I impressed with many of your comments and I am looking forward to being a part of the group.
I Am a proud owner of two corvettes, a 2000 coupe and my wife has a 2002 convertible. The 2000 has 150k on it and has had some rough idle when stopped at lights. I do have an aftermarket K&N air system. RPM's drop to 300-400 and then back up to 700. I had the codes run and it said o2 sensor. So I replaced the front left and right sensor. I was also told to replace the mass air sensor, so I put a Grat air sensor in. I still have the idle issue. I then replaced the fuel filter for GP. After reading many of your comments it sounds like I should have the car dyno'd, but before doing so I would be happy to hear from you if you have any suggestions.
Thanks,
Jack
