OK when the car is cold it will start right up but if i don't let it warm up it starts to lunge forward in first gear. Then when it is all warmed up and running great, ill turn it off and go somewhere for like an hour and when i come back i have to keep priming the engine until it warms up.

I just had the TPS changed and new Fuel Injectors.

Any clues to what im talking about??

No I have to keep reving it up the entire time

 

You mean you have to hold the pedal down to get it started, then keep your foot on the gas to keep it running?
just for shXts and grins, check to see if all of your sensors are plugged in and the wires look good and not mixed up. my truck has two temperature sensors that look similar, one is gauge, one is computer engine temp sensor, and when the computer temp sensor failed, it ran as above and got 1 mpg.

 

gage sensor in driver's side cyl head, computer sensor in intake manifold near water neck (on my tbi trucks)

 

the sensor the computer sees is called CTS (coolant temp sensor) and sits close to the t-stat housing on the intake manifold. you can test your CTS using a volt/ohm meter, use the search on this board.

 

Do you hear the fuel pump prime for 2 seconds when you turn the key forward but not on ? Maybe something in the pump busted allowing fuel in the lines to flow back into the tank or canister, canister could be full of fuel.

 

Thanks for all the Info Guys. Tried everything but a new fuel pump but its going to the shop today. Ill keep you posted as to what happens
