Hiya Steve, on the v6 the rear bank of spark plugs are often ignored during a service. Could well need changing.

Hi Eric
Thanks for the reply.....

I can say that the back 3 have been done as Ive done them myself......
Ive just started her now and she started no problem, no lumpy running etc and thats been over night......

Just put it down to a "bit of dampness on the leads" ( unless you've been in a heatwave ! ) and forget about it unless and until it happens again

Hi I have had that once or twice in the last 6 months but it clears after 30 seconds , I was advised to check the wiring on the coils where the connector block is, just pull the outer rubber section back to make sure there is no chaffing of the harness on all 6 coils
