Anyone have any idea on what would cause a trouble code for the MAF low input? I have a 2001 a4 1.8t. I just changed the suction pump, and coil pack on cylinder 1 and it runs fine but i still get an error code for the MAF low input and the check engine light stays on.

Appreciate the help.

 

trying cleaning the maf with some cleaner there are maf cans u can buy from autozone

 

I will try that later today. Thanks. Would that more than likely throw that low input code out? Or could it be something else as well?
