Hey all.. I am completely stumped on what is throwing me these codes.. I have a oil leak somewhere and I believe it is my pcv valve as oil is forcing its way out of my fill cap... In cold weather car revs 1k-3k over and over again... Dont know what else to do.. Gonna change pcv valve and egr soon. I've cleaned my mass air flow sensor and my throttlebody.

P0113 - Intake Air Temperature Sensor 1 Circuit High Bank 1 - Probably an electrical problem.
P0304B - Misfire on #4 - Probably bad coil/plug
P0306 - Misfire on #6 - Probably bad coil/plug
P0430 - Catalyst System Efficiency Below Threshold Bank 2 - Probably catalytic converter damage due to misfiring.
P1299 - Cylinder Head Overtemperature Protection Active - Have you let it overheat?
P0304B - Misfire on #4 - Probably bad coil/plug
P0306 - Misfire on #6 - Probably bad coil/plug
P0430 - Catalyst System Efficiency Below Threshold Bank 2 - Probably catalytic converter damage due to misfiring.
P1299 - Cylinder Head Overtemperature Protection Active - Have you let it overheat?
P0304 and P0306 are misfires at cyliders 4 and 6 respectively. I would recommend swapping coils and plugs on all 6 cylinders with OEM Motorcraft. P0430 is related to Catalytic Convertors or O2 sensors bank 2, probably catalytic convertors if I were to guess based on what you said. As far as the P0113 and P1299, someone more knowledgable than I will have to help you out

With two misfires on the same bank (4 and 6 drivers side) I suspect that the valve cover gaskets are leaking oil into the spark plugs. I suspect that this problem would also cause the P0430 code. (It has for me.)
"P0113 - Intake Air Temperature Sensor 1 Circuit High Bank 1 - Probably an electrical problem." I agree. Maybe loose or the connector needs cleaning.

Okay that makes sence because it is leaking oil but i thought maybe my egr or a clogged pcv would be causing that.. on cold starts the car wannts to stall and bogs from 1k-3k rpms back and forth sometimes if i dont give it gas it dies and it blinks battery...

Are 4 and 6 on same bank? Another thread showed 1-4 passenger side bank and 5-8 drivers side bank

You are correct. Cylinders 4 and 6 are on different banks.
