Correct. Stock PCM has TM ENABLED. I will agree that some of the sensors going bad will cause timing to be pulled. IAT for instance. But there is no certain amount of timing that will be pulled if the o2 sensor goes bad. It's not like if the o2 sensor goes bad it pulls 4* of timing off the bat...Or even at all.
That is incorrect. Any time you have an ses light on it does not pull timing. If you have an air ''injection issue'' or if you have a code set for a vacume leak then you're STFT and LTFT WILL be WAAAAY off. Pegged out to be exact.
Sure I would not mind looking at it for you.
I'm not tring to sound like an ass either. So sorry if if was.
But either way, The o2 sensor in the cat is simply there to make sure the CAT is working properly. It does not control fuel or timing or anything except a light.
