Re: pulled codes, please help
To confirm a bad MAF due to code 56, disconnect MAF, start engine and let it idle for 3-5 minutes, shutdown and rerun a KOEO self-test. If code 66 shows up, the MAF is kaput....if it doesn't....wiring problem tracing time...This is the code that is causing the problems you've been having @WOT...LUK
