nothing hitting…switched condesores still same problem…plugs arew 3 years old but good..i used an inline spark checker spark goes away at just off high idle…going to switch coils see if problem moves to lower cylinder…and i will test coil..as for cleaning pionts i use 600 grit sand paper clear clean..set at 20 thou..when it is working at idle i tested spark strength had spark arching out to about half inch before it would start to break up.
