Erm, slight mistake, my friend who turned up yesterday for the running problem, it not a V6, i counted all 6 coil packs in a line so that makes it a STRAIGHT 6 an me a numpty :D :D

So any one got any idea's, still need to read the live data.

Cheers for all your thoughts in advance

Andy

OK, im a NUMPTY NOW, YES ITS A V6 (vr6), sorry to confuse anybody, its a narrow v6 not what im used to, hence why i called it a straight

Update people, cleared the codes, and started her up and within 30 seconds 1st code :

Description on my SO diag machine:

17748 camshaft/crank angle sensor wrong combination of ecu's P1340

(leave to run a while longer then the other codes appear, but if the cam an crank system is faulty then of course im gona get misfires are i ).

When you start it up, runs rough missing like a tractor,3 mile run, 10min drive etc an she smooth again,so even if she is a warm engine, as soon as you turn the ignition off, then 2 mins later start her again, same problem 3 mile run, 10 min drive etc an she smooth again.

Each time you turn her off, shes a lumpy tractor, my friends terminolg.

Any views or comments ?

Thats got me stumped, as Ive never heard those symptoms before. From your codes, I suppose the starting point would be to replace the Crankshaft Sensor.
