I'm having a strange miss going on with my TA 89 350 TPI. It only seems to come in a slight throttle after it comes out of cold start mode. as soon as the engine really gets up to temp. I'm kinda leaning toward the mod in the distributor as the car has a recent tune up. Sound like i'm on the right track with this? also ran a comp test and got no red flags there so i'm confident its not a mech problem the motor has only about 70K on it.
