Default '04 limited turbo throws code p0522 and p0508

Hello i'm new to the group. But it has been very helpful to. I have an 04 touring edition turbo and i've only had it 6 weeks. It's use with 57k miles on it now. I've replaced the o2 sensors and car still stalls. shows new codes p0522 and p0508, which are the oil pressure and idle air. has anyone else had this problem and what should i do to fix?

It could be a number of things.Oil is burning, oil is leaking, your oil pump, or your oil sensor.
If its burning i guarantee you would know, so thats probably not it.
If its leaking you would be able to see it on the ground.
Ive personally never seen an oil pump go though, so i doubt thats it.
I say replace your oil sensor and see if that fixes it. Probably will
Is it still covered by warrantee ?

P0508-IAC VALVE SENSE CIRCUIT LOW

The IAC valve is located behind the throttle body. Check to make sure it's fastened on securely and all the wires are tight. If it looks good, take it off and clean it or just replace the valve itself. If it's not working properly it will cause stalling problems.

Get a TB gasket and take the TB off. Then remove the IAC and TPS. Before you yank the TPS, crack the throttle blade and note the position. The TPS has to seat in the TB to line up correctly with the Throttle blade so it can track the positon of the throttle. anyhow when you put the TPS back in it has to line up correctly and you will know by operating the throtle by hand with TB off the car.

So clean the TB and the passage ways in the TB where the IAC is. Also wipe down the pintel on the IAC so it seats correctly. Carb cleaner works good.

Your car is stalling and the oil pressure drops because the load bogs the engine down. Clean the TB and IAC and I bet your stall goes away as well as you oil pressure code. worst case get a new Mopar IAC and replace it, do not get aftermarket on sensors and electronics.
