Update... I have had the truck for a few weeks.
Pinging is alot better - sprayed the MAF with electronic cleaner and added Lucas to gas. The air cleaner was also not snapped down.
It was really hard to shift when cold, it had regular gear oil in the transmission. Removed and replaced with MERCON ATF and it shifts like butter.
Was also getting door ajar warning. Did a search, sprayed with lithium grease, fixed.
