WHY DID YOU CHANGE IT AND WHERE DID YOU BUY THE PART. AFTERMARKET AIR FLOW SNSORS ARE MARGINAL AT BEST
i got it on ebay and the reason I changed it was a check engine light was on and checked codes and that told me it was the mass air sensor .
I just went out side and ran the engine with the mass air flow sensor not conected and ran great so discounected the battery and conected the mass air flow sensor and drove it better but didnt go to far
The code is for the system or circuit affected , NOT necessarily the part. I agree with globalhelper about the part(s) , OEM is usually best.
any ideas what it maybe Im a little mested up now that i put the old one back in and didnt stall and when i put new one in it it stalls out
