Re: running rich...new O2 sensor
No to most...I read the plugs...it's rich. I've got it narrowed down to either a sticking injector, or for some reason, the ECM is telling it to run rich. (maybe the engine temp sensor?...I'm not sure how to test it) There are no trouble codes (OBD-I), so that's why I'm thinking bad info to the ECM. Any thoughts would be welcome...I've got plenty of time to wait, just no time to work on it...thanks
