my '85 had the same problems. unfortunately, my culprit was A LOT more expensive. my timing belt jumped a cog and it caused my motor to blow a hole in the side of the #4 piston. $1,800 performance rebuild. i'm in the process of re-installing the motor right now, and i'm taking the extra steps...new vacuum hoses, new radiator hoses, new t-stat. i'm hoping that'll clear up the problem.
