MAF 33/34 codes
I have this thread on the electronics section but I thought I'd put it here as well since I do some DYI Prom stuff with a Moates emulater/TunerPro. Can you guys offer any insight?
Upon a light cruise or letting off the gas pedal, all of a sudden I get codes 33 or 34 and the car starts sputtering and bucking then it goes away. On the scanner it appears that when this failure happens the MAF values lock in place, sometimes high sometimes low. I am trying to check the wiring from the computer to the MAF sensor, changing the MAF (swapped out with an old one, no change / have a new one on the way). Already checked the relay's. Can you guys make any other suggestions? Thanks!
