1994 IDIT, 152,000 miles. Auto. Engine all stock. Truck starts and runs perfect, idles great and drives perfect until I floor it. When it reaches a higher RPM it sputters and makes a sound like an exhaust leak snd sputters, hesitates and has reduced power. I have to let up on the accelerator coast a little bit and then can continue driving. It returns to normal after about 20 seconds. Does this on both tanks. I always add a fuel additive when I fuel up. Have changed the fuel filter and fuel pump (factory mechanical). Injection pump and injectors replaced 22K ago by previous owner at the dealer. Any ideas? Thanks for your help.
