My 1989 9000s is stumbling once or twice in a mile. I have replaced plugs, distributor cap and rotor, and wires. I suspect it is vacuum related but I can't find the problem. The check engine light comes on and then goes out when I back off the throttle. The shift up light comes on also even if I am already in 5th. Any ideas?
