Hey guys..I've got a prob and maybe you can help me out. I am the proud owner of a 92 300CE and recently ran into a problem. Lemme describe it to you. In the morning, when the car has been sitting out all night and it's cold, the car starts at the turn of a key. Although, when I get in my car for the rest of the day or when the car is WARM, the car will act up! I turn the key and the RPM's shoot to 10 then just drop..I turn the key again and it's about 10 seconds of crankin and crankin before i get a sign of life out of it. When it finally tries to start, it stutters like it's have trouble turning the engine or finding it's footing. The wires are new although the plugs aren't Bosch but i'm workin' on that. I sell car parts (Thepartsbin.com) and people have told me that it could be the Idle control valve or a fuel pump relay. Could anyone tell me specifically what the problem is? Any help is much appricated! Thank you!
