Clicks a couple of times then starts has new battery

07 cts will not start after replacing timing chain, the engine pop's then keeps cranking until I turn off the key.

Car wasvran with no oil and now it knocks

The car runs great, but after 30 min of driving I got this message "Trans Hot Idle engine". and it started to shift weird.
The Trans fluid life is decreasing faster than normal

V6 3.6. Using 5-30 Mobil One. 51000 miles. I am having to add more and more oil between oil changes. No leaks and no obvious oil burn out the tail pipe. Is the engine running too hot? My temp gauge appears normal. Starts fine. No performance problems. Am I silly to think it has to do with the smog system? Dealer has no definitive solution.

What else do I have to do so I don't get code po430

Yesterday driving to a friends my Cst started riding ruff an the traction control flashed on.. now every time since then when I drive I cant pass 60mph.
