Had a bad valve in my 1991 Honda accord Lx did the valve and now cant seem to get it to idle right and the check engine light wont go out and the idle is high
Should be a idle screw on the throttle body. right next to the accelerator cable. also make sure your cable isn't pulled tight keeping the accelerator opened slightly for a high idle

I have known when the distributor starts to go bad it will not fire 100%, that could cause your failure in good gas mileage!
SOURCE: Have 92 Accord LX idles low when running and problem cranking
does it have a throttle body or fuel injection?

not enough info. Typically, CO and HC together can be the result of poor fuel control or misfire, or worn components such as O2 sensor or catalytic converter, but without more data, repair recommendations are likely to waste money and not achieve success.
