timing light didn't reveal anything. I tried disconnect brake lights just in case that circuit was causing a problem. No difference. I tried just moving it about in driveway making the truck rock. Both back and forward make it cough. And that's with and without the brake booster on manifold vaccum. Without I put a piece of line on with a round punch jammed into it so the engine doesn't lean out.
I am kinda stumped, but will keep monkeying with it.
Any ideas, no matter how odd (relating to this problem

) would be appreciated.
