Thanks for the help,
Although I have worked on my own cars all my life I have just started working on my Benz.
Rotor and Dist cap were pitted and dirty- cleaned and scrapped them so I hope that is good enough for now, wires look good and will check plugs tomorrow.
1 - can I test this resistance with a standard meter and what should the readings be.
2 - Generally how do I do a fuel leakdown test and finally where do I find the accumulators.
thanks again for any help
