Before you start I did search the forums and couldnt find any help with this problem. I have a 2004 EX with 145,000 miles. When I first got it was was hitting mpgs in the 30s. My last fillup brought me 21 mpg. Here is the fuelly chart: http://www.fuelly.com/car/honda/civi...gepoge1/299035 along with mods in notes that I did during that tank. I also have timed my 0-60 at 12 seconds which is terrible compared the the average 8 seconds. I miss my mustang right now cause it was 7 seconds. And the Mazda 6s that I passed on to get a civic got 6.5 seconds. Any idea what is causing this problem? The spark plugs are the Denso Platinum TT and I put a Fram air filter in on this most recent tank which was my worse tank(old filter was also FRAM but wasnt the Extra guard one. Old one had pollen buds clogged in it though)

Re: Poor performance and fuel economy
Stock Civics have never been champs at sprinting. 12sec is not surprising at all. Mustangs and Mazda 6's have larger engines than you probably do. Now if you had a turbo or engine swap, that's another story. Do you get top tier gas? Any additives besides the SeaFoam?
Oil is good?
Unrelated, but timing belt is good?
