Why did you change other bits?  Was fault there before you changed those parts?


Cam sensor sounds favourite, but get codes read before you replace parts.

Taxi Driver is in Swindon, he could probably read the codes for you.

In which case if vauxnut wishes to contact me I'm sure I can try and help ... :)

Now have a MaxScan GS500 - which I don't yet know fully how to work ... and the ELM327 which I do .. :)

I have chatted to vauxnut a few times, sometimes I park up close to where he works and he comes over for a chat.....

I dont think its cam sensor, as he doesnt get starting probs (ie prolonged cranking) or g/b going into limp mode.

Also when mine had a cam sensor issue....it ran on 4 when it eventually started....

Tho willing to read any codes that maybe stored if he wishes  :y

PS..... Parked up twice tonight where you work.......you didnt come out for a chat.......wasnt the fact it was peeing down was it  ;D ;D

possible oil in plug recess due to cam cover leaking, the reason I say this is mine done exactly the same due to oil, causing the rubber shrouds over plugs to rot or perish allowing spark to track to cylinder head and cause miss fire for approx 15-20 secs, mine would then be fine allday untill engine left to cool, then would miss fire again.
