my air filters has been changed.....I might need that seafoam and cat..I called a dealer here in Michigan for my 4x4 switch...$84 bucks

Ouch. There's a switch on ebay right now for like $10. I'd try that before giving the stealership any more bailout.

Yes it is. All 1996-2000 Chevy and GMC trucks and SUV's went to the Vortec Heads when OBD-II was introduced for better emissions, fuel economy and power output.
