PO302 Cylinder 2 Misfire

[jojid]

So I was preparing my car for my stage 1 so I decided to
Upgrade Coil packs
Change Sparkplug ( RS Ignition Kit from ECS)
European short Shift Kit (which shouldn’t have anything to do with issue)
OE Performance induction package

Now I have CEL Cylinder 2 misfire
I already tried following:
I gapped sparkplug twice
Tried using old sparkplug
Swap the 2nd coil pack back to original

any suggestions on what else I can check

odd thing is car runs great

Make sure you don’t have an intake leak

He has a CEL for a misfire in cylinder 2. What would an intake leak have to do with that?

Ok. Didn’t think about intake leak. I did remove my intake. I took out the snow cover plate and changed the induction tube

that’s what i thought but I’m running out of ideas

Vacuum from the intake can cause misfires

On just one cylinder?

do you know if this goes into any hose?

Nothing goes there

Why did you even change your coil packs? The stock ones work perfectly fine for 500 - 600 hp MK7's

I didn’t know that. I just turned 50K... thought it was a good idea

I think everybody reads the APR hype that they produce 10% more spark energy and think that helps go faster.
