I recently put in an original electronic ignition into my A15 engine. I put new NGK plug wires and new NGK plugs. But I used back the same coil that was their with the old ignition with points. I'm getting a little problem though, when I start the engine warm it up and go on the road shift from 1st to 2nd at about 2500-3000 rpms and let go the acceleration pedel between gears the engine shuts off. I even get this problem throughout the day while driving at normal temperatures. Basically the problem exists when I rev the engine at a high RPM and let go the acceleration pedel quickly. The problem only started after I put the electronic ignition. Does anyone have an idea what can be causing this? Could it be because I used back the old coil? Should I buy and electrionic ignition coil?
