Running more rich than normal... tuning help?
Hey guys... was out for a drive during lunch today and noticed my A/F gauge shoot almost completely Rich. I was on my way back from lunch and the car was very warmed up. This could be a fluke, cuz I have never seen it run this Rich before. I know my A/F gauge isn't terribly accurate (so no replies about that please) so to be safe I looked at my PowerFC -> Sensor Check -> O2 sensor and sure enough it was reading up to 1.05 Volts when I push the gas down 1/2 way. Normally it's at .89, .9-ish... which I think is good at 14-15psi. The good news is I don't smell excess gas... but, to be honest, I didn't stick my nose near the tail pipe either.
So if this persists... what could have suddenly triggered this. My O2 sensor going? I certainly don't want to take a chance of making it Lean out - so I'm weary about lowering my inj duty (which was at peak, 49%) Just fyi, I have 1300cc secondaries, and an upgraded fuel pump.
Thanks in advance... it's good to have the help.
