    Give people a chance to reply!

    Why are you going round unplugging things anyway? Is there an underlying problem with the car? Have you had a fault scan if Q2 is yes?

    If things don't improve when the MAF is disconnected then it's not at fault. What was the car scanned with? When was it last serviced? Spark plugs? Coil packs? and so on.

    You'll just use more petrol as the ECU uses a default setting if the MAF/AMM has been unplugged or detects an open circuit.

    What was the car scanned with?
