Advice needed
I have been having issues with my 93 c4 (lt1), It will at random shake really bad and loose power as well as running really rough, and at idle it sounds and feels like its about to stall. This problem only happens randomly while driving, it will suddenly start happening and after awhile just go back to normal like nothing ever happened. It will do it randomly at different temps and rpms it just seems random. The best lead I have on it is that it might be the optispark but i’m not sure. I wanted to see other people’s opinions before i go pay for a new opti. Ill try to put a video in, it doesn’t really show the shaking that well but it shows the rpms
