HEY guys I NEED HELP !!!!!!! I have a 1995 tahoe with a 350 tbi. It has 250,000 kms and it runs like crap. It runs better in park then once you put a load on the motor the truck tries to die. It runs alot better when cold and if your driving at higher speeds (thats if it can even get to like 80 kms), and you put the pedle to the ground it sometimes dies or will down shift and try and take off but wont go anywhere. I have un plugged the o2 sensor and no change in running, i have un plugged the knock sensor and no change in running. The EGR is new i have done the distributor, cap, rotor, plugs,wires, coil, tps, map, tbi gasket, checked the fuel pressure its at 7 psi,grinded down the grounds, timed it, checked for vaccum leaks, and it doesnt throw a code. If there is anything else i could try PLEASE let me know. thanks.
