OK so I have a 2000 323i.. rough starting, push the gas a few times and everything clears up.. so.. pulled the plugs sat morning. #1 dry, #2 damp, #3 flooded with a lot of gas, #4 same issue, #5 damp, #6 dry... Went to BMW and purchased (2) fuel injectors for the 3 and 4... now 3 and 4 are dry but when the car sits for a hour or more the misfire is there... otherwise the misfire is gone.. I think Sat I will have to pull everything apart again and look at the other cylinders/injectors..
said all that to say this: you may want to pull the plugs when the car is cold and see if the injectors are leaking down into the cylinders..
are you having the same issue?
Well never mind... I didnt see the date on your post..
