V6 Won't Idle

Drive it for a bit and see if DTCs come back before we start condemning anything of that nature. They don't often go bad, but it is not out of the realm of possibility.

Sounds like a plan. The main reason I'm leaning towards that is that other than the horrible gas mileage, it runs perfect when it's not stalling out on me. When you go back a while after it was stalling it'll start right up and run perfect again.

It got me to work fine tonight though.

Sounds more like an input issue to me than an output issue. Most of the Throttle Body DTCs are fairly accurate and if it wasn't able to control the engine that well it'd most likely default to limp home mode.

What do your fuel trims look like? (Short Term, Long Term, and if you're scantool provides it "Total Fuel Trim" would be helpful.)

I keep having the code P0453 come up.

I took a picture of the scan tool screens. IDK if they will give any insight but here they are.

P0453- EVAP System Pressure Sensor/Switch High Input

Well that's an odd DTC to get...

Saturday when I was having trouble one thing I tried was switching out the fuel pump and the defog relays.

Today I tried to use my defrost and it wouldn't turn on. So it seems maybe my fuel pump relay was bad, but I was still having issues on Saturday after I swapped out the relays so I guess I'm still not sure.
