Rough idle and multiple codes

Hello, can you be clear on the codes again, are you saying, P2279, P0507, P0301, P0302 and P0304? Any Codes P0301-P0304 are cylinder misfire codes per cylinder, i.E. P0301 Cylinder #1 Misfire etc.
Also, do you have access to your own scan tool?

Just to add to this, if you have misfire codes on multiple cylinders and the P2279 which is an air intake temperature code which is most likely caused by an air leak then we need to start with this.

More than likely you have a leak on the charged air side of the turbo. Basically, if you are losing pressure from the turbo to the intake it will cause a rich condition and you can have a misfire.

Basically, it thinks there is a certain amount of air coming in and matches that with fuel but if there is a leak then you will not have that much charged air and so it be a rich condition.

Let's monitor the o2 sensor data and see if you are on the rich side and then use soapy water on the charge tube to look for bubbles.

If this all checks out, then I am attaching the testing for this code which is what we need to run through.

Lastly due to the rough idle, we should check for a vacuum leak. This is a similar test but here is a guide for checking for a leak:

Let us know what questions you have.

Thanks

No problem. Let us know how it works out. Thanks

Ambient Air Temperature Sensor is labeled the Outside Air Temperature Sensor. This is going to be a 5-volt sensor with ground. I'll put up the diagrams for it.

But this is the first time you've gotten this code, correct? It's strange those others would disappear and a completely different one show up. How is the wiring harness on this thing, you don't notice any contact points where it may have rubbed threw the harness at all? On this Outside Air Temp Sensor, you should have 5-volts on the green/white wire and the other green/brown wire is a shared ground circuit. If you unplug the sensor and just lightly touch the pins, never jam a multimeter lead into a connector, you should have 5-volts with it disconnected. Thats it 5-volt reference wire (or feed). These sensors are usually on the front of the car, most of the time in the front grille area. You'll be able to identify it by its wire colors. This code is for a circuit issue. If you're missing its 5-volts, then there may be a wiring issue, corroded connector, etc. That would explain the other random codes. And by switching the coils around you've identified that it's a bad coil causing that misfire. Smart move by the way, moving that coil.

Okay, it may be like Kenny said, the turbo boost pressure is leaking and you're not getting other codes because you're just not driving it right now, The P2279 is an Intake Air leak code, and definitely can be coming from the turbo leaking into the intake. We call vacuum leaks "false air" because the ECM doesn't see them, but the oxygen sensors will and the ECM will increase fuel due to that, therefore causing a rich misfire.

Can you post a decent picture of it? Is it near the oil supply line for the turbo? In yellow is the supply line and red is the return line.

Something else I noticed that is strange, are those live data readings with the car running? Because all your fuel trims are reading 0, which is not good, either the scan tool is not able to read all the data, or the ECM doesn't have full control of the fuel system. The sensor on the Intake is the Intake Air Temperature sensor, the Outside Air Temperature sensor is ambient outside air used mostly by the A/C system. Thats what the p0070 code is for, so you had 4.5 volts with the Intake Air Temperature sensor unplugged? that's a little low for the 5-volt reference circuit,
So, what are all the codes you're getting right now? pending or not.
the fan issue may be because of that ambient air temperature sensor being out of range, since it's part of the A/C system.
Go down to the APP sensor on the gas pedal and just check to see what the 5-volt reference is down there. On that sensor, (its 6 wire) you should have two 5-volt ref feeds.
Also looking at the Front 02 sensor, which is a wideband sensor is reading 0.980mA, that's indicating a lean fuel mixture, so that's still pointing at a vacuum leak here. Usually for a vacuum leak like this that you couldn't find with soap and water, i would use a smoke machine on the intake, I'm assuming you don't have one?

I'm not sure how accurate these numbers are but I do see a Short-Term fuel trim bank 1 sensor 2 of 99%, depending on how this ECM calculates its fuel strategy, either that's a lack of correct data, or the ECM is adding fuel to a lean mixture. The FRP (fuel rail pressure) looks within spec for idle, it should go up to 2,000PSI with higher RPMS.
