I've been having idling issues, had vac pipes check and wiring , along with coolent temp sensor changed etc, did a compression check and it was low on cylinder 1, found out to be a crack ring on the piston. Car use to drive ok , when warm idle would drop to 600rpm and sometimes stall and it happens when dipping clutch at times from changing from 3 to gear 2. Going to go forge now as engine can't cope with power.
