Well, I got codes across the board.
159-Mass air flow signal higher or lower than expected.
121-Throttle Position sensor signal higher or lower than expected
314- Thermactor air system not operating during test on bank #2
334- EGR sensor signal too high (closed position)
But... No rich or lean codes? wtf? that's like, the entire "air fuel mixture" calculation system throwing codes, except the o2's?? They are more or less brand new. Only got a few months on them. I find it hard to believe my ecm is cobbling together a decent tune out of that mess...
And in KOEO it scored a 1-1-1 system pass, so it's not running a default tune (failure mode).
I wish my damn multi-meter still worked.
It find out how bad off those readings really where. I've gone through 3 MAF's already and still don't have a good one, that sucks.
