Hi all been working with Justin still on my truck after the 3200 stall was put in. Anyways we had the tune almost done and I had a free day off work to clean the throttle body and decided to do the airbox mod while I was at it. Now I have idle hang at 1000rpms when coming to a stop and it will idle only once I get to a complete stop other wise it will keep at 1000rpms. Also when starting it up it shoots up to 2000rpms and then idles.Could we have been tuning off a dirty throttle body this whole time or did the cleaning/ airbox mod really throw off my flow that much. I feel bad because it was almost taken care of. I wish I never messed with it but I did get rid of my idle roughness.
