My 1995 E320 wagon for the first time ever just turned over, started and immediately died, then turned over and over and would not start. Using the accel. pedal when cranking caused the car to start, except for a big cloud of blue / gray smoke for a second. The smoke went away and the car ran fine. Since this episode it is starting normally without any smoke at startup or when revving.


Why?

The smoke is probably from the extra gas. When was the last time the spark plugs were changed?

At around 40k miles, Bosch Platinum 4. Checked them at about 60k miles, burning very cleanly (light brown deposits). Car also has K&N filter, another 40k mile addition, and new Interstate battery; oil changes every 3,000 miles.

Get rid of the K&N filter. See previous posts. It will cost you a lot more in the long run than what it is worth.

Get rid of the Bosch Platinum +4 plugs too and install the proper non-resistor plugs specified by MB.

Buy OE or OE equivalent parts. They are reasonably priced from MB parts specialists like Fastlane.

Are K&N's bad for a m102 also? Or is it just the newer technology engines?
