hey can any one help me please i have replaced my coilpack twice this time i just replaced the one coil istead of the whole thing and its gne again after 4 days of having it in there i dont understand it its the same two cylinders each time 3 and 6 and the thing is it happens randomly like went to the shop was runing sweet got hme still fine went to go out 1hr l8r started it up yes happend again lost the same two cylinders by the way it was a brand new coil and i have the series1 engine with the series2 coilpack can anyone out there help me please
On a VN, the factory ones are square. Upgrade it to the VR coil pack, replace your plugs if you haven't, check your leads and then see how you go. If failing that, it might be the DFI module.
so would faulty leads cause the coil to pack up coz as soon as i put a new coil in it will run perfect for a bit then do the same thing thats why im confused
Nah not the leads. Sorry didn't read that bit properley. Does it cut out? I had this problem about 3 months ago, the engine kept cutting out on idle and while driving and sometimes wouldn't start. I thought it was the DFI to ECU loom, so i did a whole transplant of the loom, that didn't help, so i replaced the whole coil pack from a crappy stock VP one to a brand new bosch (VR) coil pack and brand new DFI module. Cleared it right up no probs.
a fautly lead can cause problems also. i have this problem on the VS, all new coils and problem goes away but then slowly i get a high speed mis and can feel engine surging a little under moderate to high throttle settings, changed coil and problem went away but was back a few weeks later, have changed plugs previously and didn't solve problems, have new leads going on this weekend and failing that a new dfi (although i replaced a dead dfi last year) i also have a newset of MSD coils sitting here but i don't wanna put em on untill i know the problems fixed cause i don't wanna fry em
i dnt think its the dfi coz it has dne it to two complete units and i have replaced with new ones each time and it still keeps hapining so i replaced the single coil and it ran fine for about a week and then packd up again so im going out today to get new leads plugs and coil and see how it goes
Leeds generally brake down under load when there're stuffed - like going up a hill the car starts to missfire, cough and fart. Killing coils - hmmmm are they getting too much voltage? Is the altinator charging OK - no other electrical gremlins running around in the car?
alternator is sweet and i havnt come across any problems other than this i gt told today tho that if the leads are old and cause to much resistance then the coil will get to hot and pack up as for to much power to it dnt knw havnt had that checkd will do tho its just it keeps droping the same 2 cylinders 3 and 6 as i said i have just put all new gear in today plugs leads coil etc and its runing sweet so time will tell i supose other than this im out of ideas oh selln it is another optoin tho aye lmfao
Hey guys, I am having the same sort of problem in my series 1 vn. Yesterday it dropped 2 cylinders, so i checked the spark on the coil pack. It seems the bottom 2 have no spark at all.. Does anyone know if I will have to replace the coils and the DFI module, or just the coils? Also, does anyone know roughly how much the parts I will need are? Cheers, Sam
VN ignitions are known to be defective. as Cobez said, replace it with the later system, which means DFI and coilpacks (the later systems have 3 separate coilpacks). the other thing that could cause it is a faulty ECU. you can get these checked, Petroject (i think they're called) did mine and found a problem. they fixed it and it was all good afterwards.
