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?
