07 5.3 LTZ - 200k miles. dod/afm turned off (hp tuners) as well as the back o2 sensors. just added a quarter of oil yesterday, and my girl tells me to come look at this when i started it. never had it do it before. just changed the solenoid for the EVAP that's in the engine bay. P0449 code is why i changed it. figured it couldn't hurt.
This is what I fixed earlier:
only other codes are: P0036 x2 (Heater Control Circuit Sensor 2) & P0054 (HO2S Heater Resistance Sensor 2)
it's running rough. i dunno what to do with it.
here's some oil on the ground after startup & a pic of inside the exhaust directly after
This is how it sits now.
4wd. LTZ. 3" level. 33's/17's (interco's m16's 50k on them, give or take - which i love) - trucks gave me absolutely no trouble, until now. i do regular maintenance on it. changing the plugs/wires tomorrow, or the next day. only things i've got left to change. just changed the coil packs the other day.
Some changes it's been through....looking for a set of 18" black/chrome mavericks, because the 20x12's were WAY too wide on a level
