Im trying to diagnose if the problem with my car is the car...or me. I have a 93 cobra and when I'm cruiseing....any time the rpms are below 1600 the car bucks and misses. I cant cruise smooth unless i hold the rpms higher. Then it is smooth as can be. When I am sitting at idle the car sits about 1100rpm which I think is high. The car is all stock minus 3.55 rear gear, exhaust and k&n. I believe the timing is advanced to 14 degrees. Am I crazy, or does this car have no low end power, or should I hold the gears higher? Thanks
