Miller, I replaced the Egr and vac lines 3 months ago. Runs alot better now.
Cyclist, that probably won't happen as I am looking for low hanging fruit first. Great concept. Btw Suburban has a lower Cd than the shorter Tahoe.
Vacatiotime,i am not sure which trans is in my truck. I dont think it tells the computer what is going on, when I first got the truck it the shift point was really high, my mechanic adjusted it to shift nice and low, (od at42mph). It has a rebuilt Tbi, new manifold/gaskets, and I cannot find anymore vac leaks. I need to check fuel pressure, and replace the fuel filter, though I dont think that is it.
It has a hard miss, like ignition, then it sounds like its flooding. I am looking into testing the dizzy.
