I also eliminated the misfire as since the...

It just has a slights stumble at very low throttle before say 1500 rpm. I put shorty headers on the truck so...

    94 tbi 350 sputters and stalls with advance line plugged in...

    Oh I timed it at 0 btdc. I used a timing light. But it sputters and dies when shifting into reverse and drive. I "adjusted by ear" and its run better but a little rough still. Could it be the ecm? It's practically the only thing I haven't replaced

    Truck runs like crap.

    Well I installed a new distributor. Truck runs great. I still have a little idle surge while truck is in drive. I am assuming that's because of the headers leaking pretty massively and the o2 is sensing a lean Condition and over compensating. In park truck idles perfect at 660
