Thank you! I first changed all the spark plugs, it was due anyway. The diagnosis reported cylinder 3 misfiring. Deleted the code, let it run a while, same code came up. So I did what you said, swapped coil 3 with coil 4 and no misfiring anymore! The code didn't even follow the coil, it's just resolved itself.

Thanks! I currently have a 1999 BMW 328i, but I’m going to buy this generation of BMW this May. I may just do a complete tuneup on it when I get it. I love BMWs, because they are extremely easy to work on and well engineered. The placement of parts are very well thought out. Well, except for my vehicle replacing the starter was not fun as it was in a extremely difficult area. Other than that, it’s a very easy car to work on.

I get the misfire code on cylinder 6 sometimes running map 7 only with E65 mix. New plug coil still there, going to try the injector swap. E90 335i FBO JB4+MHD E85 BEF STAGE 2 FUEL IT

[@MrNicoe36cabrio]

May solve your problem , but carbon build on the intake valves at that cylinder will cause a missfire code too....So you have to start at the beginning; clean intake valves. Than study the code behaviour. good luck!

[@SidwSace]

Scan it. Replace the coil above misfire. Good to go.

[@TR8CED]

Quick question; My misfires go away after a second or two on idle. These codes do not show up via normal obd2 or MHD. This misfire usually occurs on startup 50 percent of the time but instantly goes away and comes back periodically on idle. My assumption is a failing injector but its hard to confirm since I don't know which cylinder

[@Jables77]

Also, can there be fuel on a plug that isn’t firing? My coil, plug, and injector work fine…CAS module not telling coil to fire.

[@supasupra9543]

Just replaced all six of my ignition coils on my 08 bmw 328i and it’s works the shaking and rough idle is GONE !!! Cost $200 bucks at auto zone 😂but my problem are gone thx 🙏

I have a 2011 550 F10... got drivetrain malfunction. Took to dealer they said it was coil number 7. I decided to do diy and change all spark plugs and coils because it seemed simple enough. The drivetrain malfunction is gone after the change but the engine light is on. The car doesn't idle well and if I give it half throttle while driving the drive train malfunction comes back up, it will clear when I restart the car. Today I went to local shop said cylinder 7 and 8 misfire. Also cylinder 7 had moisture looked like oil... Maybe gas although it didn't smell like it. What would you recommend? Injectors and/or carbon? Valve cover?

It would be smart to replace all gaskets related to the valve cover. If you have the knowledge and time, you should also replace your oil filter housing gasket. It is prone to failing.

Mine runs rich too. You can smell it. I've replaced all ignition coils twice in a year. It fixes the intermittent shutters for a little bit and then it comes right back. Done the swapping thing. I'm going to look at the injectors and see if that keeps causing my issue. And replacing the O2 sensors help?

I did however ad miniature air filters on my aftermarket charge pipe and a hks vacuum BOV ......I'm now running a small mix of e85 and I can't stress enough these cars are insane, the intercooler swap is MAJOR I have an intake temp gauge and with my 5" ducted sealed cooler o all that air Rams in I get roughly 10deg c above ambient after hard driving if I did this before on stock I would do 1 hard pull and it would just keep soaking exponentially until it was 2.5times ambient which is just like park and don't boost its a really really important part I think and I must confess I got a cheap eBay one to experiment but it has worked so well I just kept it, I'm in hot part of AUS too so if your on a budget I'd consider the eBay copy , I may be in the minority/lucky though but it's mad gains never heat soaks it's like it's not able, if u want your engine to ever cool down more and the cooler cause mine is sealed meaning it will suck outside air into intercooler then radiator turn your aircon on for a few minutes and watch the temp drop dramatically

[@joshtheld]

Could by coming from cylinder. I have very similar issues on my e90 right now. Can is misfiring, shaking at idle( 800 to 600), will also shake in reverse. However, once I pick up speed I don't feel it anymore. So yeah, I scanned my e90 and it says the misfire is coming from cylinder 1. I'm gonna start with swapping cylinder 1/2 coils tomorrow and go from there.

[@rubberyfaceimbred]

I have a slight miss on idle only then it goes away when warm no codes come up is this really anything to bother looking into? I'm changing plugs soon but I'm surprised the code never comes up maybe it's just rich startup pops?

[@dhalsim-1]

Sounds like a vacuum leak, possibly from the manifold. The misfire will occur on cold start-ups usually through one of the gaskets, which will then expand as the engine heats up and re-seal the air leak. I had similar cold engine misfires which turned out to be the manifold gasket going to cylinder no. 2, so went and got all intake manifold gaskets replaced and that sorted the problem. It may not be the same fault on your own car but it's certainly something to look for. Good advice is to get a smoke test done for vacuum leaks.

[@ps3dayday]

[@legendondubz]

I need your help folks? I got bought an abandoned 98’ e36 M3 S52 with two bad cylinders 1 and 2. I have replaced and switched around coils, spark plugs, and injectors... No changes. Only diagnostic test done so far is coil ignition test. And they are good. Symptoms found were moisture on tip of spark plugs 1,2... perhaps gas or coolant. Overheating... I believe bad Thermostat. Codes pulled are P0300, P0301, P0302. I tried unplugging coils 1,2 while engine is running and it did not change engines timing. I also notice a small hose that goes somewhere under the intake manifold is hanging around. There is moisture under oil cap every time I check, and lower radiator hose stays cool at operating temp. I plan to replace thermostat, search for vacuum leaks with smoke tester. I am thinking it is intake gasket leak, or valve cover leak, or vacuum. I’m hoping for responses or opinions and praying it’s not head gasket. Help......

[@lt1hass303]

what did it end up being ?

[@NS-77]

I have a misfire or rough idle on a cold engine but not getting any codes, when the engine has warmed up it runs and idle's fine. Do you think this could be the vanos solenoids? Seen your video on replacing them and looks like an easy diy. Engine only has 42000. Or would you recommend checking plugs and coils first?

[@bulkhogan5]

Long time owner here. It's normal on a cold start. n54 starts up in open loop mode with no o2 sensors and tmap, etc metering the car. After a minute or so, it transitions to closed loop and then emissions are in place smoothing it out. If you have no codes, you're fine. If it was vanos, you'd know. You'd get a dash CEL and limp mode. You'd also see 2A82 or 2A87 codes.

[@chrisrodgers9564]

Could be a vacuum leak.

I have a 2007 e91 328i that misfires once warmed up sometimes coupled with a whistle noise when it happens. What could this be? No engine codes atm

[@mattriella6776]

the whistling noise you're hearing could be one of 2 things.....the water pump......or you have an " un metered air " intake leak.....this will cause misfire codes if more than 1 cylinder begins to misfire a predetermined amout of times , check all your intake connections on the filter box and connections leading to the intake manifold if it's turbocharged , check to make sure charge pipes are secured to the turbo's

So what about misfires but no codes? My car misfires on cold starts every day but once it gets to normal idle it stops and there’s never any codes or issues with it. Been like this for a while.

dsuther13 Take your engine out! Replace with new One!

Maybe new spark plugs

[@armandomarquez2517]

What did it end up being?

[@husseinel-hajj7818]

Surely this is late, but I've read somewhere that an air leak could be the culprit here, cz when hot the seals and gaskets expand and block any tiny spaces where the air could escape

I had a misfire in cylinder 1. I changed the plug and coil and still the same. I haven’t checked the injector but I need to replace 2 oxygen sensors. Will this still misfire the engine?

[@hectorgalvan7614]

u need to erase the code

WJAT TYPE OF MISFIRES WERE YOU GETTING. IM GETTING BUCKING/JERKS AT RANDOM SPEEDS

[@LeonZedd]

Did you figure out the problem?

[@patienceisalifesaver9582]

Leon Zekavica not yet i have it parked. I believe it’s my vanos solenoid, it started acting up when I cleaned them.

[@LeonZedd]

Have you checked the cable that connects to your ignition coils? Maybe that could be the problem why you missfire? I had the same issue pop up so I’m getting the car checked now . If I find out the problem I’ll let you know

[@patienceisalifesaver9582]

Leon Zekavica yea please do
