Im going to look at a 92 auto this friday. Ive already seen the car and heard it run car sounds great and has a fresh rebuilt motor with 94 block less than 2000 miles an trans overhaul 20000 ago the body has 140000. My two questions are one i know theres a thread on doing a manual swap so if i could get a link that would be great. Second is the guy said it runs good but it has high hydrocarbon readings and it runs rich. He told me he had a chip burned by sct but it didnt fix the problem of running rich. He sais he cant find any vacuum leaks im thinking possibly fuel pressure regulator plus it has highflow cats. Anybody experienced this or have any suggestions?
