workingonit's MAF is same one that's been in mine for over a year. I took out the OEM to clean and installed the temporary MAF. Since it's been working fine, I've left it alone. City MPG is ~16 city. Highway MPG has reached as high as 24 true MPG.

Post your actual codes. Someone may have a history on them. Plus, it's known the harness has issues with water.
