This one is still confusing me (not hard to do). The car is a 2.4 jtd 136bhp version, it pulls hard fom low revs, then at around 2500 rpm, the car starts to pulsate the power with it coming on and off until it goes past 3250 rpm, then the injector light comes on and when you change gear, the car goes in safe mode until you release the throttle and all is fine again until you rise up the rev range.
To make things more confusing, it only seems to pulsate when you rev the car hard (not thrashing)
Sometimes the car does not pulsate, but there is a loss of power and the injector light comes on. I know it could be the MAF, but whether that would cause all of that and the safe mode driving, not so sure.
The car does not emit any smoke from the pipe, and the turbo whistle seems ok.
Before alfa take any of my hard earnt pennies, any one got any ideas
