I will set it back tomorrow to see if it fixes it. Just strange it wanted to do this all of a sudden and nothing was changed. Let you know tomorrow.
I will try that as well to see if it?s fixes it. I did not want to splice my wires on the maf pin out and see many people now using the adapters. Maybe it?s just faulty we will see. Thanks again.
Set dfco to 284 still does the same thing and the maf code still comes on. New adapter harness comes tomorrow. Hopefully this fixes the issue.

No go on the new harness. I’m beginning to think it’s maybe something mechanical. A read a broken spring can cause this on Ls1tech forum. Going to check the maf wires come from the block maybe something got exposed or touching the headers. Any thoughts?
