engine starting to buck
At first every time i hit a bump it seemed like the check engine light would come on. Now it seems to drive fine sometimes, usually on smooth roads, then rpms go crazy and sometimes just dies. I recently changed o2. I get code 179.
My rear fuel pump just died. Could my other pump be going out too, or am i way off? I have 92 f150.

I'll try and help a little bit here. I've done some code pulling and trouble shooting with the KOEO and CM through the computer. Code 179 shows: Right side still rich, at leanest adaptive limit, during part throttle. Use this website to further find the problem. Also what engine do you have? It sounds like a V8 either a 302 or 351.
