Okay, here goes, Read this carefully, and thanks a bunch ahead of time.
Start truck, idles ruff, voltage goes up an down, truck spitts a bit, put in gear move it 5 inches, push in clutch idles fine, go figure, thats when cold that part is not a big deal, the BIG deal is, start it warm or cold, 3 to 5 seconds engine light comes on, thats ok, drive down the road normally get into any higher gear let the RPM's drop down to about 1,500 use the throttle to power your way back up to speed, hold throttle, 3 to 5 seconds or so engine light goes off YES!? NO!!
starts to buck, jump REV funny, looses speed, let off gas about 2 seconds engine light comes on, down shift, punch it, and your off like a freakin rocket? what the heck is going on??? please anyone have any clue? also truck did over heat at one point, put newer radiator in it, now runs fine, but if you sit with AC on it will over heat sit without AC on its fine..
