Well, its still throwing code 48, maf sensor circuit fault, despite having fitted a new three wire connector and cleaned the sensor... Ive got a new Delco sensor arriving hopefully tomorrow, if that doesnt solve it I cant see what else is in the circuit that can go wrong! apart from the ECM being faulty.. the car starts, runs and drives faultlessly, the only clue to the fault is the SES light, cooling fan on constantly, and the code 48, other than that no problems at all, its running in closed loop at the moment, Ive heard that vacuum leaks will throw this code but which hoses/pipes should I be checking? any thoughts anyone ???
