Hello. I have here a Punto 1.2 8v 60ps Bj 12003 It runs in idle run quite unevenly When driving it dwindles from time to time but above the 2,000 revolutions it goes quite well to drive. Now I took down the air filter box and the spark plug plugs were plugged off I could determine that in the first cylinder was installed other candle than in the other 3 Add to this also the on the 3rd cylinder a different ignition cable plug. I have now ordered new candles and cables Kön could that be the solution? On the 3rd cylinder a cable with a long shaft was plugged on it. On the other cable were on it with a short shaft. Mfg
