I have two 1.6 Ford Focus with the same fault both cars have fialed MOT tests due to unstable RPM above 2200 to 3000 both vehicles are unstable it is impossible to hold the correct rpm , both vehicles hunt in this rpm range , no faullts are logged lambda , throttle pot and amm seem normal it appears that the injector duration is fluctuating excessivly , i have tryed clearing the KAM and disconnecting the battery , anybody else seen this , seems to be a software issue ?
