Actually the sputtering was the external wastegate opening and closing due to the unequal length header. This is what my tuner said and in order to get rid of it was to switch to a EL header. I thought i was loosing power but it was a placebo effect.

finally after a long while, i found the right workshop which diagnosed the problem correctly.
I changed cyc 1,3 coilpack and it was solved. yippiee.
I could have changed just 1 but since I got 2, the mechanic just put both in.

*high boost high rpm stutters.
if high rpm but no boost - ok
if highboost low rpm - a little stutters.

it is not the fuelpump sock or spark plug or maf or fpr vacuum hose!

the best part - i used non-subaru original coilpack. i bought it off ebay at less than 40usd. (just make them an offer )

those coil packs are not worth it. I bought 4 they only lasted 2 months. The old ones are in again.

Similar issue.. would get 4 miss fires. Changed out two coil packs with new ones from rock auto. The original OEM coils I never changed started working again. The two new coil packs only throw the errors..

Looks like that random connector might be for the EGT probe, which i imagine if you have an aftermarket DP, you wouldn't be using. At least thats what the EGT connector on mine looks like on an 02 wrx

You need to wake up, pull up a chair in front of the car with the hood open.

Don't do anything............just look and think.

You are rattling off countless things that are not installed correctly, or are current issues.

A. Why is your vacuum so high?

B. You already replaced the coil packs with new ones......still get misfires.....so you put the old ones back in.......NO.

C. I bet that oil feed line/ hose to pcv is not the only hosse that is not secure

D. Injectors were leaking....fixed.....how? Did you replace the o rings, are you sure that is the only injector that was leaking?

E. Exactly what bkr7e plug are you using? 11 series......if so it is not going to matter how you gap them as those plugs are for NA subarus.

You need to successfully knock out those questions above.

Also what is that connector leading to....EGT sensor? I hope you have 2.2 khom resistor in the opposite connection because if you don't the ecu is throwing you into limp mode as it is seeing cat deficency.

It would take an O2 sensor to see P0420 code (cat efficiency) right?

I understood the EGT signal would set a light but not limp mode. The EGT is not used for tuning and has no effect on it.

oem egt too high will absolutely limp mode. this is to protect the preturbine cat, the turbo itself, etc.
