My blazer has thrown an EGR code along with an MAF signal out of range. Anyone have an easy (possible) solution for these. My EGR was sticking 100%, and MAF showed 24,000 over normal...im confused!!!

well your EGR is held on with 2 10mm bolts. use a long extension with a swivel joint and you can pull it right out. spray it liberally with cleaner and scrub with a toothbrush and it shoiuld unstick pretty easily. when you replace it use a new gasket, but spend the extra money and get the one with the screen in it.

as to the MAF out of range... i aint got a clue. Sorry.

 

LOL. that was my thought on the MAF. Still acting up. I got the EGR issue fixed, so thats one problem down. Now I just have to replace the battery, coil and Distributor cap and rotor. And my work schedual doesn't seem to give time for repairing my truck...

 

Im not too good at diagnosing mafs. 1st thing i would do is buy some maf cleaner and clean it. Other then that...time for google.

 

maf cleaner or isopropyl alcohol & Q tips over the very fine wires. There's a DIY for it I think. Search it up!

 

Q&D electrical cleaner worked good for my MAFs

 

Thanks everyone. Sorry about the delayed response. Been out beating my head in the rig for a few months. Now the Suburban died. MAF is reading in range now after a tedious, yet through cleaning
