i have an 07 LTZ and i just jumped in the truck to go to work and when i started it, it felt out of the ordinary. kind of a rough start. then i put it in reverse and i felt the roughness get worse. whole truck was shaking and the engine was pulsing along with the RPMs being a bit high.
of course my Driver Info Center computer lights died a few weeks ago so theres no diagnostic capabilities. has anyone ever experienced the engine issue and stabilitrac lights at the same time?

 

First I've heard of this. Best get it scanned. How does it run/drive after initial start?

 

shaky.

 

Probably need to take it in. I assumed you checked for obvious things like loose or disconnected plug wires, etc.

 

Check the wiring harness adjacent to the front drive line.
My guess is a wire came out of a clip that happens to power the fuel pump.

The guess comes from the wife's 07 Denali doing the exact same thing.

The service guy said they replace a section of wire, get it off the front drive shaft, all good.

Could be B.S. but warranty fixed it.

Mr. Wizard just mailed my cluster back to me. I'll plug 'er up tomorrow, see if my $169.00 (incl. ship) fixed the DIC.
