Title: Miss fire 3.0 MV6
Post by: Sir Popple on 08 February 2010, 15:09:15

Hi all, Ok this all started Saturday I have a miss fire so i replaced all spark plugs this did not fix the problem!! I have just done the paper clip test, but do not get any fault codes other than the 12 and 31. So i have now removed each spark plug cap to find that cylinder 1 is not firing. should this show up as a fault code if the DIS Cap is faulty? or could it just be the lead?

Thanks

Is it just 1 not firing? If so, HT leads.  If a pair aren't firing, DIS pack (depending which 2)

older ECU doesn't have misfire detection, so won't raise a code for it

Hi, have only tried the drivers side as you know the issues at getting to the others, the other 2 on the drivers side are working fine

Never, just wish the nutter of an engineer that decided to root the wiring over the top of the spark plugs was within reach!!!!

You need to find what it is first, and if the DIS Pack, which of the 3 types it is...
