My 98' Eclipse has for the most part always averaged about 245 miles to a tank from city driving, and about 300 miles from highway driving. I'm trying to determine is this number I'm getting normal, or is it time to replace my O2 sensor. I've been getting a CEL on and off for the past 2 months, and when I took it to Autozone to get them to check what code it was, the light was off, and they said they can only do it when the light is on? I thought the ECU held the code so that it could be checked anytime. Anyway, I'm now getting black scoring on my plugs, so I'm definately burning rich, and having a hard time determining my CEL. Anyone know how I can get the CEL checked for a low price?

I used to get about 350 when I was NA. Now I have no clue since the rebuild I havent tested it out.

I have a heavy foot, and have always only gotten 245 miles (city driving) on average. I bought my car as a demo model from the dealer, and it had 4K miles on it already. I never had it checked out, and always just thought the car was a gas gussler. Now that I'm getting this CEL, I'm trying to determine if I should have been getting more miles all along or not. Anyone else that is NA have mileage averages?

I average a little over 300 and I drive pretty aggressively, but that is a mix of highway and city driving

When i was NA i would get over 425 miles on a tank all highway, i could make it from my house in cerritos to my girlfriend's family's house in oakland in one tank. Now that I am turbo, i get like approximately 250-300 miles per tank, my car is tuned a little rich so i bet i could get more, but this is what i am currently getting.

Yeah, I think that maybe my O2 is screwy then. Thats probably what my CEL has been trying to tell me. Can the codes be checked when the CEL is off? My CEL goes on and off intermittently, so it's most likely some sort of emissions code I assume. I want to get it checked without taking it to SATAN.
