Hello all, my 2.2 started running poorly on start up when cold, like it was chugging on 3 cylinders. I cleared the oil breathers a little while ago . when I whipped the coil pack off I found the plug wells full of oil... The usual story. Gasket replaced, plugs replaced, coil pack replaced, still doing it. One moment its fine, then like a switch has been flicked, no power and chugging on 3, engine light on.
Had it plugged in at garage, the only code it pulled off was c0100 which I can't find referenced anywhere.
I'm open to suggestions what to try next? I bought this car a year ago at random since it was cheap and mot'd but its really grown on me, and I don't want to scrap this one!
