I have an 86 auto with the 2.6L and a timing chain. A long time ago I replaced the head gasket and I dont think we ever got the timing just right. It has good power at speed but has always idled like crap.
So how do you time the motor without pulling off the valve cover to find the timing mark on the chain? On my VW you just pull a plug on the transmission and time it from marks on the fly wheel and a timing gun.
