If engine is not skipping,may be clogged fuel filter,but if it run,s weak,you may need to check plug,s and wire and the timming on the engine.

If it back fire,s,and timming is correct,and no skips in motor,you may need to check around the throttle body for loose or bad vacume line,s and may be check the intake gasket for leaks,

How about apex seals

I did the fuel filter, fuel pump, New injectors did the timing spark plugs with the coil packs and cables and I cleaned the Maf and throttle body
