I have a ‘12 JKU that the CEL comes on when I get on the gas and the RPM hits above 5500. It beeps at me, the light flashes then turns off. Dealer already put new plugs and coils on just before I bought it. 108k miles. I ordered the Bluetooth code scanner to see if it shows any but it hasn’t arrived yet. Any ideas?
2012 JKU check engine at high RPM, then turns off

Have you checked to see if the underhood insulation is getting sucked over the air intake, it's happened on a couple other Members Jeeps?
No unfortunately not. I’m thinking it may be bad injector or clogged Catalytic converter.
So I got P06DA code and now the CEL stays on. Spoke to the dealer and they think it’s either the Oil Pump or Oil Solenoid. I guess the oil pump has two different PSI based on what RPM the engine is running which would help explain the high RPM CEL that would go away. Now it’s on all the time so time to replace them both since they’re right next to each other and the same amount of labor to replace. Peace of mind.
