Running rich...
New engine installed with stage I cam. After all the troubles with Haynes manual firing order being wrong and replacing spark plugs because they were black and fouled from being too rich, I still have probs.
Engine will not start unless at WOT. Runs good above 1500 RPM's but seems rich. Below 1500 it coughs, spits, shakes and dies in a hurry.
Codes:
KOEO 173 = O2 sensor indicates rich condition, right side
KOER 411 = Unable to control RPM during low RPM self-test
KOER ??? = I can't remember the number but it said rich on left side
I hade to hold the throttle open a little to stay at about 1500 RPM's just to perform the KOER test. It never completes the test and dies (probably the 411 code).
Could I have bad O2 sensors? This thing is running RICH. No visible smoke but it's an eye burner!
Please help!!! Thank you.
