My feeling is with those things
esp if they respond to tapping that
its an electrical connection in the unit
I changed all of my ceramic fuses
I got my old OVR too
New one didn't seem to fix anything
but those things are a sure bet to give some problem after 100K
So a new one is insurance
Mine definitely idles at lights better
I changed alot of old vac hoses
I cahnged the rotor & dis cap
So any of that could & should have helped
I;m also running a bottle of techron cleaner
Yep happiness is a benz purring down the road...
