Ok, I did the passes like you said in second and third. Now what do I do? Do I try to clear the check engine light. How do I do that? I haven't noticed a big drop off in gas mileage since the light went on, but it hasn't really been long enough for me to tell. I will keep an eye on that. I have replaced a few air hoses as well as this was the first place that was recommended that I start. Thanks for the help!
