Please Help Me!!!!!!!!!!

I have a 92 GP LE w/3.1. I have had my Map,O2 and throttle position sensors changed. Also air and fuel filters changed,EGR valve replaced,catalyic converter replaced, oil chnged,tune up,power steering line re placed,drive belt and my fluids flushed and replaced. Now the problem is the service engine light still comes on and whenever it comes on the car starts acting like it needs a real bad tune up the car starts shaking and jerking then when i cut it off it dosen't want to start. I should also mention that I also had a fuel injector replaced AND MY PLUGS AND WIRES CHANGED TWICE. but the car acts as if it is not getting any gas. I had my fuel pump checked it is fine. I wish some one could give me a clue because I really don't wanna car note. I love this car but I have put so much into it I am really fed up.PLEASE HELP!!!!!!!!!!!!!!!

I'm going to jump in just before I leave for work. What codes are you getting?

I had the same thing happen to my 92 GP LS w/2.8L. I would have all the injectors checked or you could test them with a multi-meter and a Chilton Manual if you know how. I could be the injectors or the maybe a crank sensor or the treminal block that the 3 ignition coils are connected to. Those are just a few options.
