Here we go again! I have a 1994 480es 2.0i automatic that will misfire when it hot only. She has had new ignition module, leads, cap, arm and plugs - thought I would start with the basics!!!
Still misfiring when hot. Haven't read fault codes yet as I abandoned it at a mates house 150 miles away!!!
Please help anyone?

This could be the crank position sensor, the hall effect sensor output drops when warm, and can lead to a misfire. Autos are particularly prone to this, as the sensor 'reads' a thin steel plate not a flywheel.
Try swapping the sensor and see if it helps.

misfiring
This happened to me. Took it to VOLVOTECH in Nomansland and the mechanic pulled open a connector, cleaned it, and put it back. No further problems.
This also happened in my old 1.8 440. Though it turned out to be air mass sensor that time.
