Hi all,

Customer complaint is a random misfire, then clears, will be fine for a few days then will happen again, and above fault codes.

Car has been to the main dealer they replaced the spark plugs (no defence made) I've compression tested it, all at 130psi.

Does anyone know weather this ecu as misfire detection (where it cuts out injectors like on the Corsa C Twinport?)

I've told the customer to go away and wait till the fault happens more often.

Little bit lost as to what to check as the cars running ok, any common faults?

Many Thanks Jason
