I have a 2000 gmc sierra with only 63117 miles on it and it barely runs. i have dont a crap ton of work to it and have gotten nowhere. its got a new fuel pump and filter. new tp and map sensor and even a new idle air control and thats not even close to all ive put in it. I even went as far as putting a new ecm in it and it still is not drivable. it will start fine but idles kind of rough. i can only drive it about 100 yards before she dies WHILE MOVING. afterwards i have to wait for it to start. it bogs down at about 2000 or so rpms and has a hard time speeding up. not to mention it also threw the code PO758 for a shift solenoid in the tranny. im about to catch the damn thing on fire so any help as SOON AS POSSIBLE would be highly appreciated. thanks guys.

Which size family engine does it have?? 4.8 or 5.3 vortec. Post back and give me some time to think or the positional issues that need to be addressed that is causing your engine performance issues.

check engine light on or off and codes in the PCM?

List all that you have done and when the problem started and was it before you did any work to the tk.
