Blinking check engine light

[dyaboy96]

I recently took my 05 wrx to the shop for clutch work and a day after I got my car back the check engine light started blinking! I took it to the auto parts store so they could run the codes for me. The code was P303 cylinder misfire!!

The car's ecu seems to be in limp mode cuz it doesn't push more than 6psi with fp evo3-16g... I have done a little research and there have been a few people having issues with the stock tumble generator valve (tgv). I did not replace mine when I did the turbo swap.

My question is, has anyone else ran into the same scenario as me? If so, what was the fix and how much? Also could there be another explanation for why my car is acting up? All help is appreciated!

When did you replace the turbo?
Did you have the ECU Tuned to run with that turbo?

BTW: If it was anything to do with the TGV's then a TGV code would be displayed

I've had it on for 2 years and the car has been dyno
Tuned with Cobb apv2
