My 98 E320 wagon runs great so far, except when it is excessively humid. Luckily that is seldom in Tucson. If it's been raining and I park my wet car in the hot garage for a few hours or overnight, when I go to start it the following happens: Key in ignition, move to start, engine turns over, engine starts and runs for about 2 seconds and stalls. Restart, same thing, then again it runs fine. This happened yesterday, it was very humid, but no rain, when I parked my car a work early in the AM. I came out and tried to start it about 6 hours later and the same sequence as described above. It took 4 tries this time to keep it running. No info on the display or check engine lights either time. The car has no other symptoms. Once it starts and stays running, it is fine. Any ideas?
