I have a 1986 190E 2.3 8 Valve M102. I have Bosch Plug wires and all Bosch for the ignition system as it is supposed to be. I tested all four plug wires, only a few months old, and got readings of 1.4Kohm on each except one! I replaced the 1 with a wire that I had put a new connector on before and that wire was 1 KOhm as the spec states it should be. I tested all the other old ones I still have and they were all 1.4 K as well, they are all marked 1 KOhm on the plug end. Now my question is why are all the Boxed ones at a higher rating than the one I replaced the end on? Do I need to go out and buy three more ends and hope they all test to 1 Kohm when I put them on? I am at a loss here as to why all test high and the same value and the one I replaced the end on tests to where it should be? Could this be what causes my shaky idle? Motor mounts have been replaced as well as all Idle related parts cleaned. Mixture is also an issue as it wanders after set so I ordered a new Hex Key set for it. Not sure why the hex key would cause it to wander as the spring still seems good in it and it does come up after set but I ordered it anyhow. Any ideas as to why I can see my hood shaking and the idle seems to stay steady but still cause roughness I am open to try other things....
