I have a 1997 GMC K1500 that I have put a new fuel pump, transmission, and engine with a bunch of other stuff to go with the engine so I could get the warranty and still have some old problems and now a new one. The old problem is the truck doesnt like to start when its hot, with the old motor and with the new one I put in, it starts fine when cold and runs fine, but once I stop to get gas and get back in to start the truck it drags really bad and slowly comes to life or starts so hard the whole thing shakes, I do have a new starter too.
The new problem I have is despite all of the new stuff in the truck and it running good for maybe a month of consistent driving it started having hiccups(best way I can think to describe the issue) but going down the highway at 65mph the rpms would start bouncing up and down only a couple hundred at a time as if I was repeatedly lightly tapping the gas pedal despite cruise control being on or even if it was off and just maintained the speed manually. The hiccups turned really hard lurching and sputtering after about a week when I went to leave for and got on the road for barely a quarter mile before the rpms went crazy and the truck sputtered like it was out of gas and lost power for a sec before turning back on by itself and continuing drive and the lurching started as well like the truck didnt know what gear it wanted to be in. As if I was shifting it back and forth between 2nd and 3rd while trying to accelerate at the same time. I have so much money and emotional value in this truck and dont have money for a newer one.
