I had a little time this morning before work and thought I would troubleshoot an annoying idle issue (bogs slightly when coming to a stop, and occasionally will vibrate the steering wheel when parked).
Using my handy iid tool to log live values, this what I see:
I can lack common sense sometimes, but I see the driver side maf is under reporting and the engine is adding even more fuel (stft) to its learned value (LTFT). Does everyone concur that driver side maf needs replaced (it's already been cleaned a couple of times since ownership.
Also, I am confused by the o2 sensor readings. These are the o2 sensors after the exhaust manifold o2 sensors, but before the cats. One is super positive and one is super negative. What is this telling me?
Thank you as always for your wisdom and guidance!
