Anyone else get an intermittant check engine light for a mass air code? Its been happening ever since I installed a K&N cold air kit. It runs fine, I just get the annoying light and only happens on the highway. Thanks.

Clean your MAF, do a search on how to clean it. What happens is that the oil from the k&n is being sucked off the filter and getting the MAF dirty.

How does one go about finding a code? Is it displayed? have to have a scanner?

You need a scanner. There are lots to choose from.

You will have to have a scan tool, to retrieve the diagnostic trouble code.
