97 Ford Escort - Pinging/knocking, rough idle
Wife drove into town yesterday, okay, came home, car started to run rough, died, managed to start and get home. New plugs, plug wires (doesn't seem like it is missing). Runs rough (when you can start it), pings if you give it gas and knocks, with a bit more acceleration, pings more, but not shaking as bad. Engine was installed (new) 5 years ago, only 50K on it now. Hear the fuel pump running when I go to start it, plugs are basically clean, not gummed up, sprayed carb cleaner around some hoses, etc., no change, and all with no service engine light or codes being set? Can't figure this out. Shook the air flow sensor tube, no change, filter is still new. Any ideas?
