312,000mi 2006 V6 4x4
Finally decided to treat the rig with some much needed upgrades!

Have since:
Flushed Transmission Fluid
New Valve Cover Gaskets
New Plugs
Upper Intake manifold Gasket
PCV Valve
Cleaned MAF and Throttle Body
Greased driveshaft axles
Secondhand OEM Running boards
New Headlights

Upgraded to Bilstein 5100 front and rear, new LCA + UCA. Running Falken Wildpeak AT4's 265/70/R17

Planning to replace Idlers, Tensioner, Possibly Alternator.

Everything on this rig has kept running for over 300K miles. Unbelievable rig

Howdy friends, Anyone deal with this scenario before or have any ideas what could cause this?
Car's running great at 310K mi (V6), turned her on this morning to find:
• CEL
• VSC OFF
• Traction Control
• VSC Trac

Had these lights turn on about 6 months ago, the mechanic I went to "doped" the o2 sensor to bypass the catalytic converter and the lights have been off since then. Dunno why they mighta turned on again randomly. Appreciate any inputs !
