I`ve checked the caps and wires. The`re all clean, no cracks and i`ve firmly pushed on the caps. i`ve put a smear of silicone grease on the caps rubber seals, (the ones that came into contact with the ceramic bit ob the sparplug), to prevent any spark jumps. Intermittent Tick-tick still there at idle.
