So I was kindly renovating the rubber pipes on my 190E, fitting nice new ones for it. However in the process I decided to clean out the idle control valve by removing and filling the inside with carb cleaner. Well what a mistake that turned out to be. Now the thing is jumping around all over the place, sometimes. 2000rpm, sometimes 700, frequently stalling. What a disaster.

So what can I do? Can I make this piece of rubbish work right (it was absolutely perfect before, I guess I shouldn't have messed with it) or does it need replacing? I tried some spray lube inside there in case I had dried it out with all that carb cleaner, but no luck.

I have also concluded the whole KE Jetronic setup is a giant compromise that should never have got past the drawing board. Suitable for a military vehicle perhaps but not a car. Rant over...
