Idragit

This is the story...I disassembled and painted my truck..relocated battery and grounded it to the frame...forgot to ground frame to engine...put 225 battery charger boost onto battery to crank the truck..thought the battery was dead, but it wasnt..so when it did turn the starter over it found a ground for that power in the computer...burnt the plug and the computer..replaced with new comp, new plug, and many new sensors...truck cranks and runsfor like 20 seconds then idles down and almost shuts off then revs up and repeats process..the catch is that if you try to rev it up while idling it backfires..I've tried everything..any help would be appreciated
