SW VR6 0 Posted December 17, 2006 Report Share Posted December 17, 2006 Evening all..Was driving home the other day and the trusty old girl started to misfire. Pulled over and managed to ascertain that cylinders 1 and 6 were not firing. Closer inspection revealed a nice crack in the coilpack. So I got a tow home, left her overnight and started her up in the morning - no problems. Just trying to figure out why there is no problem on a cold start. Could it be that as the coilpack warms up and expands, the crack get bigger and lets moisture in causing a misfire?Also, can anyone explain to a mechanical dumbass why a coilpack fault would lead to 2 cylinders not firing? Just curious!Cheers... Link to post Share on other sites
petervr6 0 Posted December 18, 2006 Report Share Posted December 18, 2006 1st question prob yes when it heats up it expands and 2nd its prob just the way the coil pack has faulted. Link to post Share on other sites

lee060 3 Posted December 18, 2006 Report Share Posted December 18, 2006 yet another coil pack bites the dust Link to post Share on other sites
SW VR6 0 Posted December 19, 2006 Author Report Share Posted December 19, 2006 Well, had the coil pack replaced - no more misfire, so problem sorted. And what a difference it makes to the performance - acceleration is MUCH better. Had to go for a burn to reacquaint myself with the old girl!! Link to post Share on other sites
