Hi guys. The names Jeff. I picked up my first rx7 today. Its an 88 vert. It has quite a few goodies on it. Pulls like a beast but it has a few little querks. The big issue is my idleing. The PO installed a new engine that now has 70k on it. It idle'd perfect untill he put an S5 uppper and lower intake on it. It idles around 2k and cuts a little around that speed while cruising in 5th. Anyone have any ideas as to what this may be?
