I have a misfiring problem in my 300ce-24. I have narrowed it down to cyl 4 only. I have replaced the distributor and spark leads but to no help.
If I leave the car undriven for a few days and start it up, the misfiring is really bad.... I can step on the accelerator and the car is bogged down and moves slowly until speed builds up and it suddenly lunges forward as normal at higher speeds. While driving, I can feel the engine misfiring but not too obvious unless the car becomes stationary.
After driving and restarting the car everal times, the misfiring disappears and just when you think it is gone, it comes back occassionally but not as bad as after leaving the car undriven for several days.
Any suggestions to look at?
Cheers
