LBZ: Blowing maf sensor

[jdlover1]

A buddy of mine has a lbz and has been going thru the mass air flow sensor like crazy. After going thru two i thought is was the edge attitude doing it. So i took that off and he has been running it stock for four months and no issue. Now racing/pulling season is starting a problem has showed back up. We figured that it only blows the sensor out when motor is under a load since everytime it has mess up is when he is pulling his trailers which weigh 10k. Anyone have any ideas why its doing this? Truck is all stock other than the s&b intake,and exhaust.

dry filter or fluid filter?

its a oil filter but he has not cleaned it since he bought truck and that was about 2years ago. I thought about the filter causing it but when i took the sensor out it is dry not covered in oil from the filter

hmm i dont know unless its getting a voltage spike from somewhere

How hot intake air temps getting?

What exactly is happening to lead him to replacing the MAF sensor? Codes? Limp mode? MAF sensor codes usually point to a different issue.

he keeps throwing the code for low voltage to maf.

If the sensor has been replaced that many times it sounds like a wiring issue then if it's a low voltage code and not the P0101-Performance code.

Egr valve messing up was the problem. Egr delete took care of it
