I have a 1980 308 GTSi that I am continuing to have issues with hot starts. There are no issues starting the car when cold. Also, it will start when hot if you restart immediately. If not, it will take over a minute to get the car to start. It seems as if it is not getting the needed fuel or air mix. I have had the fuel injection checked and appears fine. Suggested were clogged injectors or valve clearance? Any thoughts?
