New to the club.I just bought a 1989 Comanche with 68,000 miles. I noticed the vaccum line going to the fuel pressure regulator is plugged. I hooked it back up and it started shaking really bad and stalled. Is that a sign of a bad regulator. Also the truck runs rough. Could that be a reason why the truck runs a little rough. It is a 4.0 2wd. Thanks Joe.
