2002 W210 surging at idle
Hi, Folks,
I have a 2002 E320 with 49,700 miles on the clock. For the last month, I've noticed an intermitant shaking while idling at stoplights. The car is very quiet, so I feel the problem as a shutter rather than hear it as a sputter. This seems to be more common on rainy days. The car is scheduled for it's last warrenty visit on Friday, 6-16 and I hope they find something. What sorts of problems would cause symptoms like these? Please let me know. Thanks for you help, Steve |

Fuel Induction Service
My 1999 E320 wagon was beginning to have an irregular idle, and I instructed the dealer to perform a fuel induction service at 92,000 miles. Although I had never performed the service before and thought of it as a gimmick, the performance and idle of the wagon is like new. Service from their website:
Fuel Induction Service (Recommended every 30,000 miles) $135.25 Cleans injectors, valves, throttle body, plenum and combustion chamber. Install BG Fuel Induction Kit. Road test. |

Possible motor mounts starting to fail.
Not that uncommon for a 50k car. DR.D

I see lots of 112 and 113 engines that need ignition wires once they have over 40K on the clock. A slightly rough, and possibly low idle are the symptoms. I get a few cars every week with this problem and a new set of wires makes them run like new. Surprisingly, there usually aren't any fault codes, but if you have SDS it's easy to see which cylinders are close to reaching the mis-fire threshold

I have a 119 engine with 63K miles on it. It started running with a rough idle after I had it steam cleaned. I've had the engine mounts replaced, as well as the wiring harness and throttle body (fault codes indicated a problem). There are no fault codes... but still a rough idle. It feels like a misfire, but no codes to indicate it. The timing and voltage for each of the cylinders seem equal. Is this possibly spark plug wires also?
