Okay so here is my issue....

My 1989 560SEL with 162,000 on the clock has all of a sudden decided to start running on less than the 8 cylinders is has. I replaced 2 plugs that appeared to be badly fouled. All the others are fine. Over the past year he (yes, my 560's name is Hans) been running a little rough when cold then fine when fully warm.

In the past 2 months its as if the car is doing something worse than just rough idling. It's like the engine like wants to die, or being starved of fuel, or something. When he's fully warm its like the engine jerks and has now a cylinder or two not firing, even at highway speeds.

Am I having a fuel flow problem? Injection issue? Any or all thoughts or questoins are welcome.

Thanks!!
