how many miles? Maybe you need to change your plugs, check a/f could be really dirty and clogged up.

also maybe you are just used to it by now...

it has 48,537 miles and i just put a K&N Filter and and i prolly need to change or clean the plugs... but dont know... so any other suggestions

could be a clogging up catalytic converter, that would cause a car to feel sluggish

[kickniteasy]

honestly, could just be you getting used to the car a bit too. I went from a 93 escort to my 03 es so that was a change of about 50h/p....my pro felt like a rocket! Now she feels slow just because I'm used to it and have driven much faster cars since then. Just a thought.

not sure if there is a problem or not but you could try disconnecting the battery and resetting the ECU and see if that brings back the pep you are missing?

I second Tsunami's recommendation. I had this problem too, Turns out it was because of a cold snap - The engine richened up and never stopped. doing this. (this was in march) When i reset ECU, it seemed to fix the issue, and I got better mileage! Also, next time your at the dealer, ask them if theres a new Firmware for the ECU - (there probably is)
