My 1988 rx7 starts cold and runs great as long as I dont shut it off. Well occasionally it sputters a little, but if I disengage the clutch and let it idle it will run normally again. Then quite frequently when I try to restart it when its at normal running temp it balks. It almost acts as if its flooded. Ive changed the plugs, replaced the air filter, bought a new fuel filter ( havent changed it yet). If I let the car cool down for about an hour it will start back up again. Anybody out there have this problem? Any suggestions?
