88 k1500 5.7-should have so much more
wondering (hoping) if someone can point me in right direction...
truck runs REALLY boggy at low rpms, but if you get on the gas it screams pretty good above 3,000 rpm +/-. therefore, normal driving is downright boggy. i had same engine in another truck, which wasn't taken care of like this one, and it ran awesome.
timing is set to zero (got rid of pinging)
new plugs, wires, cap, rotor
had a lot of carbon buildup, threw egr codes, cleared it up with seafoam & manual cleaning of egr valve.
just seems like there is a sensor, or vacuum problem i am missing. cant find it! PLEASE HELP?!
