[ian ferguson]

Hi, It sounds to me like your ignition timing is out, from what I've read from your description you seem to be getting pre-ignition. I don't know how your car is timed, has it got a distributor cap. Also I can't imagine the timing belt jumping a tooth without stripping teeth off the belt. Have you tried timing it. Hope this helps. Ian

hi ian, im told i carnt do the timing re gun, as the dizzy side of things dont move etc, as it all done by ecu?? and yes it does sound like pre ignition, what can i check re this.

I personally would get an emissions test done by some garage because you may have an over fuelling problem ,this could be down to various components within the engine management system but the co figure should tell if its running too rich causing pre ignition and might help diagnose the problem

Bring it round if your not too far away and il move that belt for you if you want, just to eliminate mate, sounds like its driving you mad

[charlotte001]

did you replug the knock sensors in or has a plug fallen off ? The knock sensors will adjust the timing till the pinking stops maybe one has failed. The problem is they're bolted to the side of the block up by the PCV system so the manifold needs to come off.

BTW is the car throwing any codes off ?
