Engine has rough idle and stalls when hot, usually after Ive been running around for a bit. I installed a new timing belt and tensioner, installed a intake plentum gasket as there was not one on there to begin with, just silicone. went through all the vaccum hoses and replaced a few. relpaced the PCV. Even replaced the upper air intake boot as it was cracking. It runs great just that low idle problem still comes back. Need my Yota geeks to help!!!
