Vibration under acceleration
easy way to tell is if the vibration is gone when your at speed coasting, then we know its not tires, but the drive line, bad u joint or front axel if you feel it on one side more then the other. at some point you'll need to get under the truck and inspect stuff. if you find grease slug all...- Scottydoggs

Fuel tank pressure vs. evap purge
if we're waiting for the evap to become "ready" that can literally take weeks, hundreds of miles and a few tanks of gas. pcm needs to see fuel level changes and many drive cycles to finally be ready. its always the dead last thing to become ready.- Scottydoggs

What did you do to your NBS GMT800 Tahoe/Yukon Today?
your in ca? you have aftermarket cats by chance? or super high miles? being you cant delete codes in ca any more, the only other option is to try adding anti fouler extensions. they pull the o2 out of the tail pipes so they read less of the gasses in the pipes.- Scottydoggs

What did you do to your NBS GMT800 Tahoe/Yukon Today?
down stream o2s are only there for cat efficiency, the up streams work with the maf to control fueling. you can remove the down stream o2s and delete their codes and never notice a thing. when scanning voltage, thats what they do 0- 9 volts over and over. up down up down.- Scottydoggs

What did you do to your NBS GMT800 Tahoe/Yukon Today?
scan the o2's with mV. (millivolts.) when you scan just the volts they are supposed to dance up and down rather quickly. in mv when you go wot they should lock in and read around 900. if they dont read close to the same the one with lower value could be bad. or if it hits 930 then drops off...- Scottydoggs

that kr is likely due to being under or over fueled, or maybe a bad motor or trans mount could cause. if that exhaust manny is leaking it can cause all sorts of fueling issues.- Scottydoggs

for that code you can try cleaning the maf, and inspect the pig tail wires for damage. kr maybe shift related, it looks to come on just before and after the 1-2 shift. being you got a hpt, do a crank learn. dont think you need credits or anything to do one, iirc its in the scanner. that gets...- Scottydoggs

has this been tuned? you got 7.9 degrees of knock retard (KR) every degree of KR, pulls 2 degrees of timing, so your down 16 degrees of timing, plus 18 is 34 degrees, and likely way to much timing, ( to much timing can cause kr)- Scottydoggs
