Old style plugs and points I have changed fuel pump /filter/coil plugs /points/ht leads /battery
SOURCE: 1990 mercedes 190e wont start, new battery, new fuel filter help
i see, we ask for help and you want to charge us for it. But if we have solved the problem, you want us to tell you how we did it. Well my time is valuable too, i figure it took me about three hours to figure out the problem and fix it, at my hourly rate of $100 an hour, yes i am a business executive that works on his own cars, it will cost you $300 for the answer.
Thanks,

SOURCE: mercedes c200 elegance 1996 model mis-firing on cylinders 1-4
I beleive your firing order is 1 3 4 2. 1 and 4 are companion cylinders-meaning the piston is up or down at the same time i.e. compression and exhaust stroke both pistons are up and even on the exhaust stroke the ignition fires in order to burn unburnt fuel/ h ve you checked your trigger. There is a good coil testing tool that is placed over the coil and has a magnetic pickup that allows you to see if the coil is being triggered-just because you have power doesn't mean that you will have spark. I would replace your ignition wires and look at your wiring harness very carefully- if it is very brittle and you see bare wires exposed that is your most likley problem because the trigger is working for 1 and 3 and has the crank senser input for all for spark plugs and the cam senser is used for ignition advance and your fuel injection system. try wiggling your harness and see if your coils start to work. wireharnesses are a major problem on mercedes benz vehicles of that era. I hope I have been helpful
