My 97 Civic EX is pissing me off. The has no mods except for cold air and Racing wires. The thing is the car runs fine, the temp gets about halfway up on the temp meter still fine. I pull into the school and let it idle and the Rpms slowly dip down and I mean WAY down. The car starts sputtering. This also happens even when it's running fine and shut it off. Then like clockwork when I start it up it's starts it's crap. I bought the car in October... it ran fine. This started around Mid-November and the only code it shoots out it the 02 sensor code. Which I had replaced. The sensor isn't bad. Just looking for some things that could possibly cause this. Thanks
