Been having numerous evap issues with my 2006 stock sti . Po447,448, 442 and 456. Last 2 were resolved with my smoke machine. Other 2 cost me about $3000 ..
The evap purge solenoid valve often gets stuck open. that is the most common failure, a simple check is to run the engine and check for vacuum going to the canister side port of the solenoid. if vacuum is present the valve is bad. also this valve has nothing to do with the EGR system. EGR- Exhaust Gas Recirculation.
also if there was a problem with the electrical circuit it would set a different code related to the control circuit of the system. voltage too high or too low. that is a simple way to rule out an electrical problem. any time you get a code for circuit high or circuit low its an electrical issue. subaru's have an extremely complex evaporative control system. best bet is to smoke test and or use dish soap/water in a spray bottle and check for leaks with the evap system under pressure..just look for bubbles
Great video - very clear and easy to understand. Thank you!

I have a 2010 Subaru Impreza and my car rattles going uphill every single time. Nothing is loose or anything any reason why?
turn the music up
Exhaust heat shield rattles plague just about every subaru. sounds like a bunch of bee's in a tin can
@@jamesstewart505 I don't have heat shields like I said nothing is loose and no heat shields
You don’t have heat shields? Did you remove them or do you have an aftermarket exhaust?
@@jamesstewart505 I have aftermarket exhaust borla type s and the cats are all new Walker brand since the others were gross and 12 years old
Currently chasing a po302 = cylinder 2 misfire
Pull spark plug #2 and visually inspect plug condition. more than likely a bad ignition coil or spark plug wire.
