I'm asking this on behalf of a mate with a red top efi engine in a vectra hes recently bought.
When he presses the accelerator theres a tapping sound coming from the top/front of the engine. Its in time with the "beat" of the engine (gets faster as revs rise etc).
Happens when cold and occasionally when idling but has been happening more when cars warmed up. It's also started to cut out when idling (after warm).
I thought it was just the usual sounds engines make till they get warm but the cutting out's odd.
Engines done 86k - its the old style vectra (S reg) and has recently been serviced.
Any ideas?
