I have a 'weak' miss on our 1988 Graduate - very prominent at idle.
I ran a compression check yesterday and got the following results:
Cylinder 1: 110 psi
Cylinder 2: 105 psi
Cylinder 3: 90 psi
Cylinder 4: 110 psi
On acceleration the car seems to run ok tho.
I am going to pull the valve cover and check clearances as well as closely inspect the #3 cam lobes.
The original cams are still in the motor and it has about 110k miles on the clock. We've owned it since new and I had a valve job done back in 1994.
Any comments would be appreciated - I'd like to get some thoughts before I pull the head.
