Hi all,

My car has a miss at around 1800rpm, feels like a bad engine mount but it's definitely an ignition/injection problem as sometimes, rarely though, in neutral at idle is has a momentary miss.

Where should I start looking for problems? Is there any known issues or points of fails for these cars?
 
Clean throttle body and MAF sensor would be a good starting point.
 
Also check your spark plugs.

Aside from the couple points from ARC to check, theres nothing really thats a common fault with the CH.
 
Thanks for help. I found the problem when i heard an electrical short (tick tick) at low revs. Had my friend put the engine under load and could see one of the coil packs was arcing to the valve cover (when engine was revving underload only). The reason was because the spark plug well was filled with oil. I've cleaned it up now and should be right until the new valve cover gasket and spark plug seals arrive.
