Having problems with your 2004 Mazda MPV ?

My Mazda MPV randomly begins to "chug" and act like it will die at a stop. the check engine light comes on. Started about 6 months ago. Seems to happen more when it rains. If I tighten the gas cap it stops and 1/4 tank later the light goes off. It does not happen exclusively after filling the tank (ie- filled it last week and it began doing this at 1/4 tank left- though the cap has not been touched since I filled it.)

Answers :

The gas cap and check engine light thing are related in terms of the EVAP system, or the evaporative emisions system. This is NOT where your surge, or "chug" is coming from. The surge could be coming from a Exhaust Gas Recurculation valve that is starting to bind or "hang up" a bit. DO you notice this happens more at lights, or when coming to a stop? if so it could be an idle air control vavle.
