I bought a 2013 ram 1500 with the 5.7, engine had bad lifter,cam and 1 bad piston and knocked but still ran. It had engine codes for the electronic throttle, trailer brakes, low battery voltage and multiple missfire. So I put in a reman engine, and now the truck no longer knocks. But It still has a miss fire, backfiring out of intake, dash says service electronic throttle, trailer brakes and low battery voltage. Along with 25 engine codes for every sensor on the truck. The truck also drains the battery after sitting for about 48 hours. I've gone over the engine wiring harness and also cleaned every ground on the truck I could find. I can not figure out what is going on with this truck. Please help!!!
