Hi
Can anyone shed any light on this one or advise, Above vehicle has developed a fault where it surges sharply on light throttle.You can also get it but not as bad when revving it stationary. No trouble codes stored. Live data looks ok ,Still Tried another maf sensor. have tried resetting ecu by battery disconection to no avail , o2 sensor switching, cannot see any air leaks and basics look fine,If we lengthen the injector pulse width it runs fine instantly. Dealer has told us there are no known issues or software updates.
TIA
