Hi John, sorry to hear about your engine misfire issue. Some possible causes for engine misfires in a BMW 3 Series could be a faulty fuel injector, dirty air filter, or a malfunctioning oxygen sensor. I would recommend getting a diagnostic scan done to pinpoint the exact cause. Once you know the cause, you can either clean or replace the faulty part to fix the issue. Hope this helps!

Hey John, I had a similar issue with my BMW 3 Series and it turned out to be a clogged fuel filter. I would suggest checking the fuel filter and replacing it if necessary. Also, make sure to use high-quality fuel as low-quality fuel can also cause engine misfires. Let me know if this helps!
