Title: 1.8t running on 3 HELP
Post by: BUDSY on 02 January 2013, 18:37: I have a 2000 1.8 20v t i bought it yesterday and it was running on 3 so checked it over and found an electrode missing from a plug so i put a new set of plugs in it and everything was fine.

today it started running a bit lumpy so ive checked the plugs again but they are ok i checked the coil packs and found that its number 4 (furthest to the right) so swapped the coil packs and found that its not the coil pack either so its definatly number 4 but the plug and coilpack are both ok the wiring loom to the coil pack looks ok too

where do I go next please?

not 100% on that :smiley: Clean the contacts up (carfully) with a knife or emery cloth and then re-connect and test it.
