Bad direct injector?

You could use the MG Flasher mobile app to log those items if MHD doesn't have them. (you just need to create a free account to use it)

Thanks!!

Let me know if you find anything im having the same codes and same issues
changed my plugs thinking it will remedy the issue and same thing
gapped to 0.22

took it to my local shop
direct and port injectors tested and clean all good
moved coils and remained on cylinder 1 for misfire

Mods on my vehicle
Port injection plate 750cc injectors

I haven't been able to do any testing because we got dumped on with snow. As soon as I can get the car out of the garage I'll update this post.

Thats a very small gap and will do less good than it's worth.

Ill try to get those custom log parameters for the misfire counter to you before you get the car back out. Hopefully before the weekend is out. So we can try to narrow down the cylinder.

I am assuming you have made a typo here as .22 is getting close to 1/4 inch for imperial and only 10 thousandths of an inch if it's a metric figure you have stated. So assuming it's 0.022" then I would if having misfire issues open the gap to the standard .030" which I believe is the stock gap if for no other reason then to see if it cures the misfire or has a positive affect. A .022" gap seems a little bit tight to me although I see internet recommendations for it.
At the end of the day when you have an issue and you have an easy no cost option to try like going back to the std plug gap you may as well do it.

Yes I assumed he meant .022

Most of the stuff regurgitating on the interwebs came from an older BMW platform. Some people (including some newer tuners) don't know any better.

Yea, tight plug gaps usually meant you had a substandard ignition system that wasn't coping.

Okay so update
New direct injector cylinder 1
Fresh new spark plugs
New ignition coil cylinder 1

when the vehicle starts up it idles rough and misfires the smooths out and I misfire but misfire at start up is still present

Here is the video of start up engine is warm. And it stabilize after a bit

 

[lucky phil]

Why is the engine producing exhaust condensation on a warm start up? whats the OAT there at the time? Misfires on start up and exhaust condensation/fumes can be a leaking head gasket. Not saying it is but it's typical of a HG leak into the combustion chamber when the engine is shutdown

 

[dismii_]

It’s a lot of condensation due to vehicle sitting for 3 days. Also where I live it’s 45 degrees so it’s quite cold.
Oat?
I checked coolant level and it’s remained the same throughout all these changes I was thinking HG aswell but I’m not sure

 

[lucky phil]

Ok I thought it was a warm start. I'd disconnect the port injection and see what happens.

 

[dismii_]

The car was already idling for a while it has reached optimal temp.
I did remove the port injection even unplugged motive reflex and same issue

I apparently missed some of the posts on this thread. My gap on my spark plugs is also .022, but could adjust them to .030. I did the misfire counter via the and misfire on each cylinder via the MGFlasher app and as you can see it's misfiring on several cylinders. This was just at idle for about 20-30 seconds. So I no longer believe this is an injector issue and maybe is as simple as cleaning a sensor (O2 or MAF) or plug gap issue.
