MAF Issues -- Unplugging Works, New Replacement Does Not? Tf?

[DamienH]

Car almost spontaneously developed an issue where the engine would bog over 2k rpm and had a super rough idle. Unplugging the MAF immediately fixes the issue at hand.

Bought a brand new replacement OEM part, and the issue still exists with the new part installed. But simply unplugging the MAF connector continues to be ok.

What else do I need to look for here? Already replaced the sparks/coils cause I initially thought it was an ignition issue.

Vacuum leaks in the intake tracts allowing unmetered air in. Perform a pressurized smoke test to see them all and replace all the parts leaking.

Your MAF was reporting correctly.
