Do I need to clear error codes or will they...
Resolve themselves? Didn't know another way to phrase it.
Have an '04 Discovery that has been throwing somes codes and have not been able to pass inspection. New MAF seemed to fix the lean codes but I still have a PO441 showing.
Question is: Will the CEL go out after it is resolved, or must I clear the codes with the UltraGauge manually? I would prefer not to clear them if I do not have to since I would need to go another 100 miles or so to cycle the system before getting it inspected again.
Anyone know about this?

MOST codes will reset the light themselves if the problem goes away, after about 3 cold starts. The code will still be stored on the computer, but the light will be off. I'm not sure how emissions checks work because we don't have them here, but I'm guessing they hook up even if the light is off to check for the readiness, in that case they may notice the old codes. but maybe they will see they aren't current anymore and not cause a stink. I personally wouldn't want to risk it.

Guy at the testing site said it just needed to be a cycle and the light off, so codes on the computer.
