1997 E320 W210
MISFIRE 97w210
Good Evening, Merry Christmas and Holidays!
I have a 1997 W210 which came up with a couple codes PO306. The Misfire happens at Idol and not all the time. The Check Engine Light goes one and off and sometimes blinks. But mainly runs well. I replaced all the Spark Plugs, the wires, and the coils for all cylinders just to be sure I covered the problem; well it didnt help actually is seamed worse. I have to say that I did not reset the computer before the test drive, however I didnt think that had anything to do with it. Any help in this matter would be great. Thank you all and Safe Travels.

Have a compression check done. It is well worth the labor only cost. How many miles are on your engine?
Assuming your car has more than 200 kmiles (320 Km), the cylinder heads may need to be reconditioned.
I hope I'm not too late.

a coil going out will do that.At 160000 miles I went ahead and replaced all 3, for $150 on ebay, bosch coils too.
