Well i recently bought a 99 integra ls. it had a cold air intake pipe but a stock air filter taped to it. so i replaced the filter with a cold air filter. i took off the pipe from the intake manifold in order to securely install the filter. im not sure if i put it back on correctly because i got the check engine light on. I got the code for it (P1457) which means some sort of evap leak. i dont know if it has to do with me messing with the intake or not but i have very poor gas mileage. (installed air filter same day i bought it so wasnt too sure how gas mileage was before i bought it) any suggestions? most google searches point to bad o2 sensor but i dont know. Any help is greatly appreciated.
