Nobody at GM has any knowledge regarding their PCM systems and the EVAP vapor cannister issues?

Way back in early January 2005, our then new 2004 Chevrolet Suburban registered a "Check Engine" light.
The Vehicle went to 3 different dealers for that same issue, at least a dozen times, but the...

Thought so.
Auto-Ride uses a different shock than the ZW7 Nivomat suspension.
Nivomat is self-contained, Auto-Ride is powered.

Old thread, but anyway, I'd try some of the additives first.

She's still looking like new, because of good care and it's always garaged when home.

Think I'll have some new tires...

Years ago when I used to pick up double 18 wheeler trailers at the rail-yard, the Rail Police Lt demonstrated the correct way to use a nightstick, or similar.
Don't hit or swing the stick, instead,...

Yep...solder and shrink wrap are good friends to have around.

I used to rebuild auto transmissions back when GMs were simple 3 speed autos.
Agree with most everyone else; time for a transmission overhaul. :neutral:

Dusted off the dash? :lol:

Some nice lookin' GM vehicles; TY for posting!
