ok, i found a slight petrol leak, which is now fixed, then i noticed the car was firing on 3. it must have been doing it since i swapped the engine over last week (well thats when it was on the road), so i done the following;
remove the injector plug to help locate which cylinder was at fault.
turns out it was number 4 as when that was removed no change to the running of the engine.
i took the spark plug out but it was wet with petrol (i cant understand that bit going by the when i removed the loom plug to the 4th inj there was no change.
so i swapped that plug and all leads...
no change, still firing on 3.
so i checked the injector loom plug wires all matched - 4 was different, one of the wires had blue in it, so i swapped that over with the one thats just under it that goes into the head as it seems they were both plugged in wrong
so now all injectors have the right loom plugs and it fires on 4.
but the misfire happens when i drive. if i accelerate slowly it will go through the whole rev range without a hickup, but if i try to accelerate quickly the car judders while accelerating - it didnt do this when it was running on 3 though
any ideas??
