Giving Bosch H9DC spark plugs a try/1989 300E
Just got some on order to see if they make a difference of not in my car and they should be here by the end of the week.
Car is running what it came with when I bought it a few months ago which is Bosch Platinum 2
spark plugs.
My wires are stock and may even be original to the car as is the ignition.
I've read a few post on the subject from the various Mercedes sites and my car does do some weird stuff,but I don't know if any of it has anything to do with the plugs I have in it now. It could just be that it needs attention in other areas,but I bought the H9DC plugs to at least take that out of the equation.
In the future I may just change the system over and run non-resistor wires so I can run resistor plugs as they are a lot easier to find.
