PLEASE CLEAN THE THROTTLE BODY. Mailordertuner.com runs into this all the time, drive by wire or drive by cable, when you add custom parts and custom tunes. Please take the time to clean the throttle bodies.. MailOrderTuner.com gets 2-3 calls a week on idle being just a little too low or a small surge but no one ever thinks about doing this. Many times we tell customers to please take it off the intake and clean everything inside and out!
