Hey. I have a 2000 Protege ES and my check engine light recently came on. I checked all the fuses and they were fine and then when I turned on the car the check engine light was off. Now about 30 miles later it is back on. Thoughts? Also, is there a specifc fuse called ROOM fuse.If so, where is it? I can't find it - manual talks about it but doesn't give location. I checked fuses under the sterring wheel and under front hood. Thanks.
