It realy doesnt matter whether the car is hot or cold it sometimes will start right up and then sometimes it takes a few hits of the key. then is will sputter for the initial take off and will stall if you dont feather the throttle. After the car will run perfect. the mechanic checked the fuel pumps and couldnt find a problem. He wants to replace the injectors which im sure i can do myself. I havent heard of electrical problems. I heard that the coolant temp valve? might be a cause. im leaning towards replacing the injectors that appears to make the most sense.
