ok so my 2000 trans am ls1 is throwing codes po101, po351, po352, po353, po354, po355, po356, po357, and po358.
I'm almost positive that all my coils are not bad but could my MAF cause my car to throw these codes as well? it run and drives but misfires bad. I thought it was just bad plugs or wires until I seen the codes. any info will help and thank you

5.7L with h/c/ ls6 intake

ok so I just crawled under the car to check all my wires when I noticed the wires running down the passenger side had been laying up against my headers so I'm going to check the wires now

What was the issue here my car just started doing the same thing

It was the wires running down the passenger side of the block. They got too close to my exhaust header and melted together. I ended up adding 6' of wire to the harness and ran it below the battery and up by the starter

Thanks for the reply, I think I've narrowed mine down to the ground wire on the back of the cylinder head I will keep you updated
