Hey,
I have a 300ce 24v with same problem.....I replaced the EHA valve, Idle Control Valve, the fuel pump/filter, the OVP fuse, and used fuel injection cleaner.....All these replacements helped the motor get to where it is---a whole lot smoother...but, i still have the warm start problem...usually takes between 2-4 attempts for the car to run....It starts each time but sputters to death....Something is definitely bleeding the injection system....most likely the injectors are leaking in my car....go figure....best of luck
