    You may just need to clean the Mass airflow Sensor. Sometimes they will get dirty when disturbing the air intake system. To clean it, just use a q-tip with rubbing alcohol and gently wipe the wire spanning across the MAFS> It may help get rid of the code. Also make sure you have a good connection on the MAFS connector plug!! Good Luck!!

    Sometimes it takes a lot more than 100 miles for the PCM to clear a code on its own. It may be simpler than you think to fix your issue. Reading the code is the one of the first steps to diagnosing issues.

    Have it read for codes and post them to the forum. You'll get plenty of help figuring it out.

    No more check engine light!! It went away on its own, even though the K&N rep said the light should have never come on. Oh well, truck runs and sounds great, thanks everyone for your help.

    I have a 08 with a 5.3 and put a aem intake on from my 2000 5.3...didnt notice no difference. took it off put a throttle body spacer on. not a noticeable difference but who cares wen you got a sweet turbo soundin whistle. put a s&b intake on and you can hear and feel the power gain! so i wouldnt say that all intakes are the same
