Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
I still have a fault with the car.. The engine managment light came on whilst driving and at that point I could feel the car was not running on all 6 cylinders (but this time engine didn't stall when I cam to a stop) The revs appeared slightly higher on tick over.. 800 rpm rather than approx 500rpm at idle. The tick over sounde and felt lumpy.. I could feel it was not firing on all 6 cylinders.??
The car engine restarts and runs sweet after it has been left for a while?
My mechanic is yet to come out and plug in his dianostics.
Could the problem be something as simple as a plug breaking down, which may account for the oily residue noticed around one exhaust down pipe under the vehicle.. Any other suggestions please .. apart from scrap it!!
