Finally got around to fixing that rough idle on my 335i

  • So I’ve been dealing with this annoying hesitation and rough cold start for months on my 2011 335i. Tried the usual stuff like replacing coils and plugs, even ran a few cans of cleaner through the tank, but nothing really helped. A buddy told me it’s probably the injectors getting clogged up from all the short drives I do around Dubai. I finally looked into getting them properly sorted and ended up booking a [Skilled Injector Cleaning Service] after reading some reviews. The difference is actually night and day – the throttle response is smoother, and that jerky feeling at low RPMs is completely gone. I should have just done this properly months ago instead of wasting money on temporary fixes. Anyone else had a similar experience with the N54 or N55 engines?
