CEL on
Hey guys, I was driving as usual today and on the highway I noticed my CEL was on. Now the question I have is should I get it checked because I'm not sure how long the light has been on but there was no difference in performance or gas effciency. Also, is there a list of OBD codes on this forum? Yes, I STFF'd too lol.

Hey guys, just wanted to follow up on my problem like a good little user. I got the CEL and turns out it was the notorious P0410. I had the code cleared by my friend/mechanic who I've known since HS. Believe it or not, my first instinct was strangely to replace the spark plugs because they hadn't been replaced for over 70k miles. Interestingly enough, I've driven the car with my new Bosch Iridiums for 3 days now with no problem and my m111 engine is as smooth as butter at 105k miles now and my CEL has not come back. Cheers to mbworld forums for helping with this problem and a host of other problems I've had
