Are you getting fuel through both TBI injectors?, Take off the egr clean the pintle and seat, maybe carboned, lots of possibilities here, on site help may be your only avenue. pS, check for major vacuum leaks, cracked/disconnected large vacuum hoses, spray carb cleaner around the throttle body to manifold area, see if the engine changes response.

I have an 88 1500 c/k and I had the same problem and I was able fix it by replacing the idle air controle valve located on the TBI. It sounds like that is your problem.
