Hello, my 1994 C280 hs a very strange problem. Every once in a while the car goes into a sort of limp home mode where it can only run at about 1000-1200 rpm. After about 2-5 minutes it is all right then runs fine. It may run fine for an hour a day or a month then it happens again. Here's the odd part it never registers any code in the computer making it hard for a mechanic to diagnose the problem. I changed a fuel relay in the trunk and another under the hood has already been changed. The car has had MB service throughout it's 73K miles. It's at a Mercedes dealer now but they have had it for four days with no luck yet. Any thoughts, or similar problems? Thanks, ndh
