Check engine light on after cat and cat-back install
hi all, this is my first post here. I have a 99 GS eclipse (2.0 NA auto). I recently installed a high flow cat and a cat-back exhaust. right after the install the check engine light came on. I've reset the computer by unhooking the battery, but the light keeps coming back. just before the install, i had the car checked out and nothing was wrong, so i know the check engine light is due to the exhaust install. any ideas?
