Misfire/overboost help

[Cclark6146]

So I was driving my car on the highway yesterday not aggresively. Started to shudder and engine light started flashing. Ok cool. Got home my laptop wont keep a charge to check VCDS (like I know how to even use it) my access port has codes for overboost and cyl 1 misfire. Found cylinder 1 full of fuel so with plugs out I flood cleared it and I could see cylinder 1 injector was pissing fuel when I shined my light down the plug tube. I think its safe to say an injector but Im not sure if the overboost could be thrown by an issue with that or if something else is going on that I need to look into. I have a stratified tune with an APR K04 that has maybe 2000 miles since installed and nothing I can see obvious with any of that

I would address the obvious first. Replace the injector, spark plug first. Being who I am I would probably do all 4 plugs and coils but that is just me.

Then see where you are.

I see urotuning has a injector service kit with all 4 injectors with seals and gaskets for TB and manifold. Think it would be beneficial to do all the injectors too rather than just the obvious bad one?

I would if….
You plan on keeping car for a while and have the budget. I prefer preventative approach and don’t like having failures while on the road. Not everybody has the budget for that approach and just fix what breaks and no more.

I would do all four injectors (and plugs) if it were me. Having the intake off for access is enough of a PITA to make it worthwhile.

I do plan on keeping the car for a while. I ordered the that service kit from urotuning. hoping that over boost deal is related. just bought a house so I cant afford any more BS lol
