P1090, P1091, P1092, P1093, P1096 (TGVs) 02 WRX
 

Hey guys
I have a bugeye WRX with a JDM ej205 swap. I've had it since last May and its been great for me. Recently I got the above codes for the TGV valves (both sides, stuck open and closed, as well as an open circuit LH side) the codes weren't there as of last fall when I last pulled codes (check engine light always on due to catless DP)
Basically wondering what it means to have all these codes, if it seems pretty apparrent maybe it got dirty or if the motors are failing. Car is in limp mode with a misfire also in cylinder 4 (P0304) I'm trying to diagnose. Replaced spark plugs and swapped coils and ruled out both. Onto cleaning injectors, MAF sensor, and changing fuel filter tomorrow and see how that goes.
