    89 Honda Accord failed for emission test for CO, in both 25/25 and 50/15
    catogery. I replaced the air filter and used car guarantee pass and drove
    300 miles. When I took my car back for emission test it passed in 50/15,
    but failed in 25/25, here are results

    Test 1 --> 2.66 -- (1.16 allowed) FAILED--> 2.83 – (1.05 allowed)
    Test 2 --> 1.91 – (1.16 allowed) FAILED --> 0.12 - (1.05 allowed) PASS

    Can anybody suggest me what are the things I can fix and test for
    emissions again? Since it passed the 50/15 test I was hoping this is a
    minor problem.
    I am planning to change spark plugs and PCV valve.

    i would do the fuel filters, air filter, pcv, plugs, distributor cap, put
    some sunoco 94 octane in it. all the cheap things that are easy to do.
    change the breathers on the side of the air filter housing too.
