JMS25th Posted July 22, 2016 Share Posted July 22, 2016 I have a 95 Honda Civic EX, 1.6 DOHC Recently, for the first time my car has failed the smog test. Here are the areas of emission test failure: Test Parameter | Result | Additional Info. Idle Speed Co | 2.10% | Greater than 1.20% Idle Speed HC | 6147 | Greater than 220 parts per million Someone told me to check my OBD1 Chord, so I did. I used the paper clip method and when turning on my car the engine light stayed solid. It never flashed any ECM codes. What is my next step from here? What do I do to fix my car to make it pass!?
