1994 Chevrolet Caprice Classic LS V8 4.3L

ive had the car for about 7 months when i bought it they just put in a V8 4.3L engine with about 40.000. Since ive had ive replaced the fuel pump,water pump, spark plugs, distributor cap, rotor,3 fuel injectors and harmonic balancer. Thats all the things on the engine i replaced and it runs rough anytime i put it in gear its shakes like crazy and it wont go over 35mph and when i rev it up it revs up then it will stop like its not getting gas. While im driving i have to have my foot all the way down on the gas pedal for the car to even move and when it does move i hear a high pitch noise coming from the engine. when i get out the car i can smell transmission fluid when it has been running for awhile but i dont think its the transmission because all the gears shift fine. Does anyone know what could be wrong with my car? Before i buy all new fuel injectors becuz thats my only solution to what the problem could be.

also another thing while im driving sometimes when i try to accelerate the engine will start knocking until i take my foot off the gas and when i try to go up hills theres no power the engine will start knocking then cutoff. When im at a stoplight or stop sign i have to press all the way down on the pedal and it barely moves it takes about 30 sec to get to 25-30 mph and it revs up to 25-30mph before it shifts into second.
i dont know if this is related to the same problem but sometimes when i push the brake the needle for the fuel indicator will shoot all the way to full then when i take it off it will shoot back down to where it was at, but usually it says my car is on E no matter how gas i put in i dont know what thats about either.

Sounds like a converter problem. It might be burning up your tranny if it is the problem.

Yeah, that seems to be a pretty common mistake. People don't realize that you had the 4.3L 262-cid V-6 and the 4.3L 265-cid V-8. But then again, he probably doesn't remember (or know) the displacement of the original small block (265-cid V8).
