Hi Stephen,
So, I did the JDM mod on my 02 WRX and loved the cleaner engine bay, however, I suspect my solenoid may be going bad because I'm having trouble with the car stalling when I clutch in at times.
My question is, could a bad purge control solenoid cause the engine to run rich, there by causing the car to stall? I have also noticed some grey smoke from the exhaust and worse fuel economy. Would it be a good idea to disconnect the line to the intake manifold (the A port) to check if it fixes the problem (meaning, would this do anything bad for the car?)
The car has new plugs, new coilpacks, new MAF, no vacuum leak as confirmed by a smoke test. Oil and coolant show no leaks and cooling system has been pressure tested. Car drives normally in closed and open loop, aside from the ocassional stalling when I clutch in.
Thanks!
