Hi Brian,

Any DTC's (diagnostic trouble codes) if you don't have anything to check them with you can go to like a autozone and have them check it, I would also suggest getting some electrical cleaner and di-electric grease, and cleaning all electrical connections. starting with ecm plug and TPS connection. then apply the di-electric grease before reconnecting. Be sure to remove cables from both batteries before doing this and thoroughly clean all battery connections and terminals.

Let me know the result after this steps. 

Alright. Send me a message on this page once you are done with the steps. 

Goodluck!
