http://www.midwayautosupply.com/detailedproductdescription.asp?3829 looks like a good deal. i figure since my idle sux yet the car runs perfect above 1000rpm and i have a pms on the way and ill be doing all my own tuning, this would be helpful. i know how to count lights and all that good stuff but this just seems a lot easier because a digital number cant be mistaken like a flash of light can. pretty good price too
