Hi everyone new to working on dodge vehicles especially cars but have alot of auto experience looking for help on this one heres whats going on,

07 rt 5.7 cant keep it runnng stalls out if i let off the gas and dumping fuel when is runing it seems codes are
-p03000 ran mis
-P0113Intake air temp
-P0058 Heater control bank2 sensor 2

I have a very metallicy slime on the inner part of my throttle body
large amounts of unburned fuel when i keep it running by 40 percent throttle atleast
here are my readings at time of p0300

IAT reading -40 is gonna be a problem. So far as the PCM thinks, it is REALLY FRIGGIN' COLD, therefore, it has to add fuel to get a burnable mixture. Fix that first, clear codes, see how it runs.

 

Okay new iat sensors in still same issue

 

Is it still reading -40?

 

no it’s reading proper temperature now

 

Your fuel trims are all zero though.... Is the engine misfiring? Was that freeze frame taken at idle? Throttle by wire? Or is there an actual cable?

 

Also, do you have a means of testing the fuel rail pressure so you can see how quickly it bleeds down after shutting the vehicle off? I too am confuzzled by the 0.0 fuel trim values. That really doesn't make sense, unless maybe the readings you provided were immediately after clearing the diagnostic codes.
