cleaned the throttle body on my 08 silverado but didnt know about the calibration being thrown off after someone manually pushes the flap by hand instead off using gas pedal so after truck ran like crap at 2000+ rpm called about 15 differant shops around town all pointed me to dealer so dealer said they would do the idle relearn for $165 USD??? ok last resot spartan autoworx said sure bring it in they would do it for free so came in no wait hooks up his scan tool within 3 mins the relearn was done truck runs fine so all u chevy truck owners dont push that flap in by hand or shops will tell you that u need $100's of dollars of usless parts and are gonna send u to the dealer in the end but just call up spartan first they are the #1 auto computer guys i love this place
