I just found this site, and read about your 300CE problems. My '91 is doing the same thing. Hard to start and when the Airconditioner is on, the car literally just sits when accelerated. I have to floor the thing before it starts to move slightly.....Did you find a solution for yours. I am so frustrated with mine that I want to get rid of it. Dealer repair shops tell me that these problems are normal for this model which I cant imagine is true. Another frustrating thing mine does is that when idling at a light, the air stops cooling properly, but when the car begins moving again, it starts to cool. I live in Dallas, TX so I have to use the air 9 months out of the year. Any help/advice would be appreciated. Thanks
