2002-E320-Shivers in Idle
- Whenever the car is stopped at a stop light, the car shivers in idle.
- At 50+ MPH, the ride is bumby. 4 tires are new purchased 2 weeks back - balancing was done then - complained to Sears and they replaced the 4 tires with a better set of tires - still the problem is there.
I changed the spark plugs and plug leads on mine first and whilst there was an improvement the new mounts made the engine almost totally vibration free.

Bumpy ride... that could be a multitude of things. Is one particular axle or particular side or particular wheel bumpier than the others?
I took the bite and went to the MB dealer. Turned out 2 spark plug cables - they did not fire at all apparently but the plugs turned out to be fine. Once replaced it is almost smooth.
The bumby ride was an issue of tire balancing. Once rebalanced using Road Master, the ride is now very comfortable.
The recommendations from them was the following,
1. Change all spark plugs ($690)
2. Breather replacement for one value ($320)
Are the spark plugs this expensive? Any ideas? What would you recommend.
Get 12 ngk7090 plugs at about 3bucks each and spend 2-3 hours doing your plugs.
pm me for the tool and i can talk you through the spark plug change.
Easy diy if you spend the time and follow directions.
Stop going to sears for tires
Stop going to the dealer for repairs
They will broke you

LOL i like the sarcasm. Yea, my car shivers in idle too. I had spark plugs change abour 10k ago. My tech says it's a sign for new motor mounts. Also, do you guys experience any "engine valve cover leakage"? both our W211 and W210 are leaking due to broken seal....
Of course, there are a lot of other possible areas to leak so cleaning and then inspecting is the strategy.
Good luck
