I'm having some weird issues.
I have brand new less then 1000 mile
Plugs
Coils
Injectors (fcp euro index 12s)
car ran great and I mean fantastic

But now I have a cyl 6 misfire at high boost high rpm

My hpfp hasn't dropped below 1900 at wot
My lpfp hasn't dropped below 70 at wot

Wtf going on now. Any ideas?

Mhd stage 1+
New crank position sensor
New radiator
New pcv valve
New vanos solenoids
New air filter
Oil catch can
Fmic
New boost solenoids


I'll be checking the plus soon. And maybe even injector. But damn it's brand new

Is the fuel pressure regulator leaking?

[xuzax]

Would that not effect rail pressure?

i have a note in my records about persistent cyl 6 misfire solved. Coil, plug gap, injector, fpr leaking

I would assume that would effect rail pressures. But I’m going to clean my intake valves soon. If that doesn’t work then I will check this. But i don’t think this is happening. I appreciate the idea tho. I will check
