I have had an IAC restrictor plate on my car for a couple years and it worked great. I just installed an Accufab 75mm TB and Plenum. I made sure to remember to transfer the plate over during the swap. Now I am back to the hanging idle issue. Is anyone else running this set-up? It has been so long since I installed it the first time that I can’t remember; does it take a while for the computer to adjust to the plate? I think it might be getting a little better but can't tell.
