check engine light comes on when car is warmed up.

I have a 94 mx-6 ls,manual,6 cyl. When the cared is warmed up the check engine light comes on. I think it might be the temp. but the radiator fan kicks on the the coolant levels are good. This is my first mazda so I'm not really sure what the problem is. If any has had this happen or knows what is wrong, i would apprectiate the info.THANKS

that happened to my car also...it was O2 sensors but cost like 800 bucks!...but i would take it to dealer to find out for sure....

yea...its prolly the O2 sensors..........go to probetalk and search for the one-wire conversion
