Hi everyone, I have a 2006 Durango 4.7L SLT AWD that idles around 800rpms then drops to 500rpms and bounces back to 1000 rpms . Then drops back to 500rpms and then dies. I've cleaned the throttle body and checked for vacuum leaks but found none. No codes are being thrown I've driven it several times trying to get it to throw a code. It is a weird thing sometimes when you start it from a cold start it runs perfectly until it starts to warm up or you touch the gas peddle.
I am almost at wit's end with this thing I bought it cheap 500 nonrunning. but in good shape, fairly low mileage and I know the vehicle the owners never had issues with it. Except the fuel pump went out is why I got it so cheap..And it looks like a dumpster on the inside still shampooing.

Problem number 2 Power Mirrors I have voltage at the switch and leaving the switch in all positions. but there is no power getting to either Mirror drivers or passangers.
Thank You for any suggestions
