I recently purchased my Corrado G60 and it runs terrible. Whenever I sit at idle for more than 10 seconds at a stoplight when I go to give it gas the rpm's just drop and i have to feather the accelerator for a few seconds to get it to jump back to normal. This also happens on the highway whenever i stay at a consistant speed, if i give it WOT the car just lurches and about 3-5 seconds later takes off. I have a air fuel ratio gauge that always sits on rich no matter how i drive, but i'm not sure if its even hooked up correctly. Also my exhaust backfires when I shift occasionally and i've been told that at above a 100 i'm shooting flames. Please help me. :(
