It had something to do with the ignition. But I decided to replace the old points ignition system with an electronic ignition module. It works so much better.
Kim Mäkynen Good that you fixed it. I did the same and fitted a Luminition system on my 105, and I agree that the car runs much better. The problem is poor quality or old condensers which give a bad spark. Even brand new ones are often bad.
Did you manage to repair the popping sound problem? What was the cause?
