Fiat Stilo 1.6 16v reg'd 29-01-2004
I have just got this car. It has a misfire all through the range but particularly noticeable on tickover. I removed the plugs and plug no 2 was a good colour, plugs 1 & 3 were black and plug 4 was oily. I exchanged plugs 2 & 4 and the good coloured plug that was now in 4 became oily. I exchanged the 2 & 4 HT coil/plug covers with no effect - no 4 will spark to the block with the engine running. There is no blue smoke from the exhaust and no obvious 'breathing' from the crankcase. The diagnostic shows 'no codes'.
I'm stuck!!!!
