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.

Read about my Frankenmotor Project and see how an M50 becomes an S50!!!

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?
