No water went in. But I did have to remove the coil to be able to fix the leak. I put back maybe I put in wrong or something idk have to check when I get home.

On my 335i I drove a few weeks with a bad cool and had no other issues. I won't mess anything else with a bad coil right, besides the spark plug.

Swap the injector from that cylinder with the one next to it and see if the misfire follows the injector to the other cylinder.

You need to relieve the pressure from the fuel system, and unbolt the fuel rail from that bank of the engine.

I mean that the fuel in the fuel rail is under pressure. If you take the rail loose from the injectors, fuel will spray out.

Lol.
Yes!
You either need to drive it around for up to 20 miles, or disconnect the battery for fifteen or so minutes to clear the code.

Did the CEL never turn off at all?
Or did it turn off but came back on?

Well you have eliminated the ignition as a possible cause. That leaves the fuel injector or too low of compression in that cylinder as the next two things to check.
A couple of other causes are a bad 02 sensor, or a failed PCM.

Something must have gotten wet when that nipple broke. Hopefully it clears itself up after you drive it a bit.
You might check the electrical connector on the #7 fuel injector and make sure that it is dry and tightly connected, if you haven't already done so.

Can it be spark plug wires?

Your car doesn't have any spark plug wires. It has Coil On Plugs (COP's)

I'm talking about what you have to click off to remove the coil not sure what's it's called.

Oh. The electrical connector. Yes. They can break and not make a good connection with the coil.
Is yours loose or cracked?

The connectors you push down the tab and just pull them off. The COP itself is held on with a real small bolt. Then just pull up. The boot will just pull off the COP and the spring that links the coil to the plug is underneath. A lot of the time when a COP is bad its because the boot is ****ed and is letting crud get down there or the spring is rusted and its causing a misfire. Should have seen the springs I pulled out of a few COPs on my Expy...

Nope all that stuff seems fine . I don't see what else it could be . It happened the same day I had to remove the coil to be able to fix the leak

I bought a new plug and coil it's still there. When I get home I'm going to remove the coil and start the car see if the symptoms are any different.

#7 is on the drivers side and it is the third cylinder from the front of the engine.

Jesus I'm ducking stupid then.

We all have "brain farts" every now and again.

Yep, 1-4 is on the passenger side and 5-8 is on the drivers side.

Lol so now replace the actual bad coil and plug. Remember to use a torque wrench on the plug. I'm not kidding.

All of the coils can be removed by simply unbolting them and removing the connector.
