yup still runs, just ah little hesitation when i push down on the peddle, it climbs slow and hesitates while climbing on the rpm gauge.

well my dad installed the spark plugs and he is a 20 year mechanic from McKee so i think they were put in correctly.

Check your timing, I had the same problem with my civic. It wouldn't pass emissions because it was running rich changed every thing you can think of and it still failed. So I check The timing and it was was off. I fixed it and now it passed emission test with flying colors, not to mention it runs like a champ.

if your off time you will misfire like that because the spark is not sparking on (time) which you will backfire and run rich bcus your not burning fuel c0orrectly!!!!!! check that n spark plugs jus to b sure
