Righto, got an N reg 1.4 Merit and it won't rev as it should.
Slight problem since i bought the car, when cold the car runs lumpy for the first half mile or so then fine.
Car broke down on the way back from shopping on Monday, cut out coming down the road. The crank pully bolt have worked loose and as such the pully was failing to make the signal for the sensor.
Put the pully back on, checked the timing. Bit shocked as the locater notch for the pully is missing and replaced by a white line any way, started car, idles fine. When you move the throttle cable the engine runs lumpy and almost cuts out, slight increase in revs but not as it should be. Engine is up to temp (fan kicks in) so what could the matter be?
Could the pully have slipped as i tightened it? Would a few mil be enough to mess up the signal for the ECU? My BIL seems adament that if the pully is off the engine wouldn't run at all.
