Major misfiring in 4th and 5th gear
« on: 05 September 2009, 21:04 »
hi, iv got a mk2 gti 8v digi and having issues getting over 70mph. Car runs fine through 1st, 2nd and 3rd gear, but in 4th and 5th the car (i guess) is misfiring/juddering and have no power at all. I litterally cant accelerate in these gears without it happening. iv changed the leads, cap, plugs, air filter and oil filter but still the same. whilst it does this misfiring my headlights will flicker (when on) and just to add to this iv twice had a mass of white smoke pouring out when i have managed to get it goin over 5000rpm at which point i lose all power till i let off the throttle and all is fine again. Somebody help!!!!

For the sake of a tenner I would try a new coil (or even a second hand one). I remember a friend had the same problem with his golf, and after trying everything (as you have) it was the coil that was at fault

i have a very similar problem on the same model. revs fine thru 1-2-3-4 but in 5th it wont rev past 5k, already replaced dizzy, arm,leads ect, so just the coil left to do for me.
