Missfire

[mo.3155]

Hi my name is Maurice from south shore Montreal, just realisez a dream, I bought a 98 z3 2.8.I love the car. i would like to know if someone had the little problemthat I have . I have new spark plugs new cam sensor, the engine runs great but when it idles there is a little misfire but not all the time. My mechanic will have a new computer this week and maybe he will put the finger on it, the problem is that the check engine does not light up and the computer cannot read it.If somebody had the same problem contact me . I just put a injector cleaner in it hope it helps.Have a nice day.
