I have a 1994 Chevy 2500 TBI fuel injected 350..idles great, runs good, but......when I take off from a stop or driving down the highway I push down od the accelerator to go up a hill I get a quick little boost of power but then it boggs and stays at the same speed. I have to push the accelerator half way to the floor to gain any speed. I checked fuel pressure. I checked TPS sensor. I cheked timing. I replaced MAP sensor. I replaced distributor with a used one....dont know if there was anything wrong with it. I checked fuel injector screens at the base of the fuel ijectors. It just acts like its not getting fuel or the fuel injectors are opening up and then closing back up or the timimg not right. HELP! Just don't know!!!!!!!
