My check engine light on the 210 came on today. Code reader showed two stored codes, P0100 for what I figure is the MAF and P0400 which shows up as EGR flow. Could the P0400 be stored in the system since May when I ran the car with the manifold off? I've had no check engine codes since then and I can't recall whether or not I used my code reader to read and/or erase any codes that might have shown up at the time. When I erased both codes today, only the P0100 one showed up again.

I cleaned my MAF the last time this happened about 14 months ago and all has been well until today. Tried cleaning it again today, but wasn't successful on my first attempt.

Anyone using the Pierburg MAF for the CDI's that's been mentioned on here before? The insert only runs about $85 or so.
