Hi All. I have a gu, pin pulled, and motor replaced. Car now has a fault code, of too much air. About a constant 5.5 volts going to the maf sensor. Have checked current maf on another vehicle, and volts around 1.0 . So am guessing maf is ok. Not sure if fuel pump has an issue. Motor starts and idle fine, no power. Does any one have any suggestion on what to check, to get maf voltage reading and adjusting correctly, please? No other faulfs registering on OBD scanner. Thanks in advance.
