p1140 HELP

Hi,
Does anyone know what can cause a p1140 (Mass or Volume Air Flow Circuit Range/Performance Problem) code? It usually come on right after i clear the code, drive around, then when i turn the car back on it pops up.

I just replaced the MAF, which was used before. And just replaced the o2 sensors thinking both of those were the problem and now I have no idea what to do.

Any advice would be great.

Also the car does idel kinda funny.

I have a 1996 318 ti

check wiring. That could be the culprit.

No, don't worry. It's cool. I'm taking it back for us.

how do I check the wiring.

Also could the new MAF be bad too?
