Please help me i have a 2006 Cadillac STS V8 and im trying to figure out why its running lean its good when i get into the throttle but at idle it is a little shaky not misfiring just stumbling a little. And what all can happen from running lean i dont want to damage the engine.

Check the intake manifold bolts. It's a very common problem.

Hey -14. Why not just post that your bolts are tight, even if you never checked them? I'm tired of this nonsense!

Lean engines will run hot and in extreme cases burn valves & pistons.

It's quite simple, when a Check engine Soon light comes on, have the car serviced. If it flashes, do so immediately. Although Cadillac dealers aren't inexpensive, they can actually provide the best value by not doing (and charging you for) unecessary repairs.

Many free parts store code readings will only provide the basics on the STS. These are sophisticated cars and the finer details often require more.

Definately ck intake bolts Prolly needs a new booster hose they swell at the back of the intake. Ck ur air filter if it hasnt been replaced lately n depending on last time u went to a dealer might need a reflash. Otherwise, inspect for any loose hoses n the pcv system
