amazak 3 Posted May 18, 2009 Report Share Posted May 18, 2009 Ok, my mechanic serviced the car around 6 weeks ago, anyways car ran awesome for two weeks then started to missfire, so the coilpack was removed and checked, apparently the coilpack mint according to my mechanic. This weekend the the leads were replaced with fancy Magnecor ones, the car drove fine all Saturday night after the new leads even had a go with a fancy Honda. Then yesterday afternoon the missfire started again. This is now really annoying me, the missfire is very erractic, Car runs fine until heats up then start to miss other times starts to miss from cold. The plugs were replaced with NGK ones BKR5EKUP something something. So could it be a dodgy plug then, what is the best way to test this? Thanks guy's. Link to post Share on other sites

rodney 17 Posted May 19, 2009 Report Share Posted May 19, 2009 it does sound like either the leads or a pac. worth swapping both and seeing if that cures it.. I have had this kinda thing before and basically as everything heats up it can break down/lower the insulation abilities and thus either arc or not provide the correct impeadance /resistance to fire correctly...

Just some info I learnt, dirty throttle body and maf sensor can cause this as well. I removed the coilpack and siliconed it to death (although there were no cracks) and the obvious cause leads and plugs. Good luck Kie Link to post Share on other sites

RAPgolfvr6182 2 Posted May 30, 2009 Report Share Posted May 30, 2009 also if you delelope a miss fire try running car at night with bonnet up to see if you can see blue flashs from the coil pack this is a sign the coil pack has split and will cause more running due to air line cracks in the casing of the coil pack Link to post Share on other sites

Ben Seabrook 4 Posted June 1, 2009 Report Share Posted June 1, 2009 nah throttle body isn't too bad at all mate - four bolts to get it off then have a good look at it and see if there is a lot of black deposits in the butterfly if so then plenty of carb cleaner sprayed in it and left to dry - job done Link to post Share on other sites
