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.
have the same problem?
