Please help sputtering
 

OK here it goes... I just replaced the, Fuel Pump, Fuel Filter, fuel injectors, fuel pump relay, spark plugs, wires, coil, distribuator modulator, coil pick-up, and the on board computerECM. !!!
Now here is the problem, while driving between 10-20 mph at an even steady pressure on the gas pedal there is a chuging and sputtering, let off gas and puh puh sputtering then clear idle, or if I give a little gas pedal pressure it smooths out and goes... Please before I spend any more money on this worktruck (210,000miles on her) what can it be????

Thanx in advance for the info :)

Not quite sure what could be wrong, maybe the ERG?

Perhaps it could be a spark problem. Check the plugs for wear, and replace if needed. Change the plug wires depending on how long it's been since they've last been changed. every 50,000 miles is a good rule. Also, one more suggestion, if you have the tools check the timing.

I know these are obvious suggestions, but sometimes the obvious is what's overlooked. Hope this helps.
