Re: Mass Air Flow question need help
In case of a maf circuit failure the ecm uses a preset value to run the motor thats why it will run with the maf unplugged, but that doesn't always mean the maf is bad I would
replace the relays on the firewall near the brake booster first, there are three... maf power, maf burn off, and fuel pump relay. and go from there.
