HT Lead fail. haha, Mass Air flow sensor, tells ECU how much air is coming into the engine and adjusts the fuel to suit.. no idea where they are on saxos.. just a common 306 problem that causes all sorts of problems with misfiring

hmm now where the hell is this MAF sensor then ??? lol do you reckon an unlocked ecu would make any difference ???

nope, its just like any other sensor, maf/map sensor is usually located on the air intake
