Hi, I have a problem with the bloody engine on my surrender monkey. It is idling erraticly and when driving at low revs it is vibrating and very jumpy to about 2000+ revs as though it is missing.
I have changed the plugs and have tried disconntecting the coil packs one by one to find the culprit with no avail. Could this be down to just a knackered inlet manifold gasket? It started before changing the rear plugs and to be honest the gasket on inspection is pretty much toast.

It is a 2001 V6 estate, the 8 XFX version.

Cheers.

Mmm, not too sure to be honest but I know the V6 can suffer with oil around the plug wells but I suppose you've encountered that when you changed the plugs?

Not sure if the manifold gasket might can cause too much trouble, I doubt it tbh.

It might pay you to also join and ask the 406 coupe club as they have far more V6's than us

That seems to be a ES9J4 specific problem, and this guy's got the ES9J4S.

My guess would be a sensor issue, possibly the CTS or flywheel sensor, or the VVT solenoid playing up
