Ok, so today I took off my JLT intake and returned my car to the stock tune as I am trying to sell those parts. Well, it drove just fine for an hour or so and then the check engine light cam on and I'm not sure why. I plugged all the sensors back in correctly and it is running normally.

Anyobody got any suggestions as to what to do? Can I trouble shoot it with my XCal 2? Any help would be awesome.

 

You should still be able to read codes with your xcal2.

 

Try reading it if not to the dealership to have them fix it. It's back to stock so they probably won't know.

One question though. How come your name is torchredv6 and you have a black car pictured and a black car?

 

Retrieve the DTC codes with the X-Cal and see what they are.

Make sure the MAF sensor's rubber gasket is reinstalled, the MAF sensor is securely mounted, the vacuum hose is installed on the intake immediately upstream of the throttle body, the intake has not come loose from the throttle body or the air box, and retighten the stock intake's clamps.
