I've had my 500SL-32v '92 model for a year now and have been struggling with a persistent misfire problem.
Basically, the car starts and runs OK but after it has warmed up it starts to misfire under load and at idle. If you give it too much gas it baulks and feels like one bank of cylinders...
In the past three days, my otherwise perfect C240 (2.4) has developed a bit of an intermittent misfire complete with lumpy idle.
The fault just occured, no hints or signs. I first noticed it when there was a momentary loss in power when pressing the loud pedal followed by one or two small...

Hi, I have taken a customers car in on Friday with a really bad misfire, really lumpy at idle and wouldn't rev at all. The plugs were changed about 200 miles ago at a dealer. I removed the coil pack and checked them - they all look OK. Thought I could hear tracking noises from the coil pack and...
