I have an 1989 230TE 8 valve, with Bosch K Jetronic, or maybe its KE,
I cant set the idle or CO, to give a smooth idle, I have a CO meter and tacho, I found the mixture control, and what I figure is the idle air adjustment on the motorised idle speed air valve (a small castelated knob ?)nested between tubes 3 & 4 of the manifold
Do I have to " defeat "the idle speed air valve to make the settings ?
I look forward to any " Top tips "
