Okay so I have a 1.6 I had megasquirt for a good minute but I decided to go back to stock I reset my timing with the CAS but my idle is still at 2k I have no idea why...before I had megasquirt I do remember the idle being a little high but then it would drop back to normal ..I have no idea how to aproaxj the problem I have already tried screwing the bolt on top of the throttle all the way down with the computer on diagnostic mode ... I tried looking for vacuum leaks and there is none ...what am I missing ?? Is there anything suggestions ...the idle hits 2k but it eventually drops to around 1500
