Figure I would check in and see if some of you beams expert could weight in on my idle issue as I am just finishing up a swap into a 94gt celica. I did not get the stock airbox so I got one of the intakes from ebay thats had the AFM adapter. I suspect my issue is vacuum or AFM related. It reoccurs when it goes from open to closed loop when it warms up. Below is a link to some videos I took of the issue. First one show a 500rpm swing and then when brake is applied its surges from 1k to 2k. Intake inside diameter is 2.95". Appreciate any insight or assistance.
Thanks
