My 1999 E46 323i 5 Speed with 140'000 Miles runs on 5 Cylinders when cold.
Once the Car warms up, i have to turn the Engine off, and restart it, and then it runs just fine. My Smog Guy's Code Reader says: Misfire on Cylinder No.3.
I have already changed the Ignition Coil, Spark Plug, Injector, on Cyl. No.3, and inspected the Ignition and Injection Harness, with no Luck. Next Thing would be the Main Electronic Control Unit, wich already has a Update on it. Since new Ones are expensive, i wanted to know, if someone of you Guys, have another Idea, Thanks a lot !
