its now running on 8 it ticks over fine but when you try to rev it it misfires slightly and wont rev? as well as it sounds like its sucking air from in the engine bay? please people any ideas dont care how strange they might seem.
1997 4.6 engine swap from hell please help
This is turning out to be the engine swap from hell. ive now replaced all the plugs leads and its not firing on the o/s bank not even 1 of them I have a spark going to all four plugs on that side as but i still have my misfire. coil pack maybe? could it be the injector wiring which to be honest i guessed them as i couldnt remeber how they went? or does anyone think the engine i got could be a dud? Ive had engine from this previous breakers before and they assured me this engine ran ok before they removed it. any ideas would be great
