Two weeks and no CELs!!! Whoo-hooo!!!! No more stuttering throttle, the smell of gas on startup is gone from my exhaust, and my mileage has improved about 1-2 mpg (although that last one might be because of the warmer weather). I'm considering myself in remission for the time being - if this keeps up for another 2-3 months, I'll call my CEL problem fully cured.

In the meantime, I ordered a Scan Gage II from Amazon which just came in. I'm going to use it to display instantaneous mileage, which will hopefully cure the S/C-induced spasms in my right foot. ;Dr;

Thanks for the winning tip, Ldub!
