I was j/w how you check the cel on a gen5 civic? Ive done my serch and the only thing i could find was on the gen6. I removed the intake manifold yesterday to replace the water house that runs under the intakemaifold into the head. now it smells like its burning mad oil. I just went to autozone and they will not check it, cuz its not a gen6. any ideas on how the hell to check it? thank you for the help.
