I wanted to get back to you guys with the solution to this problem, unfortunately we did wind up going to the stealer for diagnosis and repair
They ran the diagnostics and determined that the cam position sensor was failing due to a leaking valve cover gasket
Both were replaced and all good now, and "just a bit" lighter in the wallet
Oh well, had to be fixed and it's either keep repairing this one or turn it in and start making payments again on something newer
