87 Chevy V10 350 TBI

Kind of a weird situation here. The gas pedal is real sensitive in this truck. If you give it too much gas it seems like the truck stalls out. My girlfriend drives it on a normal basis and more than once she has had a problem with it. I have driven the truck and it seems to run fine as long as you don't stomp on the gas. But if you give it too much it seems like the air/fuel mixture is off and it stalls out. But if you have truck idling and I open the throttle from under the hood it revs up and never misses a beat. Got new fuel injectors to put in, and checked fuel pump and it seems to be fine pressure was good. Was thinking EGR but it is recently new, so I am doubting that. I am leaning towards something wrong with throttle cable, but it seems to be fine. Any ideas?:screwy:

I've had problems with the throttle body on these engines. It looks like a carburetor kit but is very expensive. Rebuild the fuel pressure regulator while your at it. If they throttle body leaks leak the fuel ratio gets out of control.
