2.8L V6 S10 IDOLS FINE BUT LOSES POWER AND BACKFIRES GOING DOWN THE ROAD

1984 Chevrolet S-10

Have changed spark plugs and wires, fuel filter, fuel line, cleaned carbuerator, changed air cleaner, oil change, doesn't know why it keeps bogging down and cutting off going down the road around 40 mph and up

Have you checked the carburator base gasket? It should have a heat grid in it and when this grid goes bad or melts down the truck won't run very good. So with the air cleaner off have a flashlight and upen the throttle and look down inside and see if it has a heat grid and if so does it look either burnt or missing some of the grid?
