PCM code advice needed
After washing my car upon restart the engine RPMs dropped and ran rough. Before shutting it off I read the codes and P0102 C displayed which is "P0102 Mass Air Flow (MAF) Sensor Circuit Low Frequency" according to the list. This code still appeared after shutoff and reading the codes again. When restarted engine ran smooth again. Back in April I replaced the CAI with an AiRaid CAI. Not sure if related or not. How should I proceed? Thanks for any and all advice!

I would check all connections to and from the AirRaid; you're losing unmetered air somewhere. The most common points are bottoms of soft rubber connectors (like bellows, MAF adaptors, etc.), where they're either not installed deep enough over their mate, or are slightly bent (not tight enough) from the natural compression of the hood on the bellows. It took me 3 tries to get my SLP system just right.

After this occurred I did briefly look at some connections etc thinking something popped off perhaps. I will go back and check in more detail. Would this be enough to make it run so rough that it seemed like it wanted to stall? Since the code remained as "C", current, I assume that it is a constant condition. Should I clear the code or not? Thanks.
