I keep getting these on and off on the GTO.... Sometimes they go away before I can even reset it (a few starts). I have been trying to figure out why and I am starting to get VERY frustrated. Between each step I would clear the code and wait for it to come back, and every time the amount of time varies.
First I cleaned the MAF (paper filter) and checked that the intake pipes were sealed.
Next I checked my PCV hoses and put clamps on them because they were not clamped.
Next I pulled the TB and checked the gasket, looked good, reinstalled.
Today I pulled the manifold and changed the gaskets... and it came back.
What's left other than a bad MAF?
Thanks in advance for the help,
John
