Need help with 4 cylinder running rich

Recommended Posts



Replace the O2 sensor first. That's usually the cause of it running rich.

Agreed--it's not likely that the injector would be the cause of the trouble. There is something sending to much fuel, and the o2 sensor is the first thing on the list of suspects.
