I have a 1991 GMC K1500 Searra SLE, 350 TBI. My truck starts fine and idles good when cold, as soon as the engine temp starts to rise idle gats rough and eventually the truck stalls. When I drive, I have to two foot it at stop signs and red lights. Also, it stalls frequently while driving. When I restart it, this usually takes awhile, it’s like pulling fuel through an empty line. Put a new throttle position sensor on when I first got the truck three months ago, wouldn’t even idle before that. New plus, wires, cap and rotor. Have yet to test the fuel pressure. Looking for advice to keep me from spending unnecessary money. This is supposed to be my daily driver, currently a lane ornament.
