New to your forum. Have a 87 pickup 22R-E, EFI, auto, Ca emissions. Truck runs great. Idles good when cold and hot. Let it sit for a bit and it Idles rough, dies and hard to start. giving it some throttle keeps it from dieing but still rough. drive for a short time and it idles good. plugs are fresh. Any suggestion on where to start. Going to spend some time on it tomorrow.
