Fitted the vac can kit a while ago to our type 4, 2.0l injection. The dissy is old and a little worn and I was finding I was resetting the points more and more regularly. Anyway, all good until the last few hundred miles. Chip has developed the odd hiccup habit. Driving along, usually in fourth steady 50 to 55 mph every now and then he'll misfire. It's as if everything shuts down for a half second. It might happen a couple of times in quick succession, then nothing for days. All the connections, earths, leads, etc are good and I suspect ignition rather than induction because it's an abrupt hiccup rather than a stuttery fuel starvation type hiccup. I'm sort of certain its not the ignition switch but will do the old diagnosis rounds until I find the problem. Step one will be reverting to points and condenser and see what happens but just wondered if anyone else has had this type of symptom prior to electronic ignition failure or has any other experience of this type of issue?
