mmm, then someone better get in here with more experience. i was just suggesting that the spark may be weak under high pressure and maybe that's causing the rich reading. there are many more possibilities though.

NO. tomorrow the check engine light should come on to or from work then i'll scan it and see what code popped up. i looked and looked for vacuum leaks, i have to check the fuel pressure. for some reason i think it has something to do with the (Mass Air Flow) Sensor.
