Misfire cylinder 1,2,3 and long crank leaking fuel from exhaust

Jr335idaily · 09-16-2018, 06:13 PM

Just bought the car couple days ago and I put 91 shell yesterday drove in town and coming home I floored it to feel the power of stock 335i but after the red light the car would shake when accelerating and would not have full power? I checked the coils and switch them from 1,2 and 3 to 4,5 and 6 and it didn't follow the misfire I pulled the plugs and all were dark but cylinder 3 plug had wet and gas smell so is it injectors or all of 3 coils, plugs and injectors, the Injectors are 7 and 9 index so I would need to replace all of them right?
Or is it hpfp?
I turned it on today and it took a long time to turn on finally did and it would idle and have misfire please help as I'm new but know the primary problems like water pump, hpfp, coils, plugs, injectors but what would be the problem [IMG][/IMG]

Sounds like a bad injector on bank one. Good luck, and welcome to owning an N54.

If it's one bad injector should I replace just one or all?
Cylinder 3 had gas inside after pulling out the spark plug so it would be the injector right? What would cause the car to shake when accelerating I'm not pushing it down a lot either. Today in the morning I went to turn it on and it took awhile then after it turned on white smoke came from the exhaust also sounded as if it was misfiring when in idle?
Tomorrow I'm going to take it in to replace the coils, plugs and injectors.
Just want to pin point what the problem is thank you for responding and thanks for the congratulations on owning n54, it's a 2009 with 74k miles

Sorry if I sound like a newb, so it's most likely the injectors right from the sound of it?

Jr335idaily · 09-16-2018, 08:52 PM

Also service engine soon came on yesterday and it's been on even when turning off and on

The proper way to do it is to swap the whole bank of injectors and code them.

Jr335idaily · 09-16-2018, 09:14 PM

Okay I will be replacing all injectors also with coils and sparks plug when I take it in tomorrow to the shop but from what u have heard from me it sounds likely the injectors are bad correct?

First of all, you need a code reader that is BMW specific, if you plan on keeping your e90 long term. Foxwell/ Schwaben scan tool, Carly, Beemer Geeks Pro Tool. Are all viable options.

If you're spewing fuel out the exhaust you have a failed injector.

Don't drive it, you will damage your cats.
