Hey guys,
I've got a persistent CEL that I can't figure out. Scanner says it's running rich, which is confirmed by my drop from 20+ mpg highway to 15 ish highway... WHEN the light come on and stays on, the 02 reads like .94 volts.
I unplug the battery to reset the comp. And the light goes away for 1,000 to 1,200 miles, come back on, I reset, and so on. After the reset the 02 fluctuates normally. I've cleaned the MAF and IAT, neither seem to remedy.
Any ideas?
