Hello everyone! I own a 1995 WRX with the EJ20G engine imported from Japan! I am having some trouble with rough idles, low throttle response and possible miss firing when the engine is cold, especially on more humid days. I replaced my PCV valve a couple of months ago and it seemed to have fixed the problem, but as of recently it seems to be giving me the same issues again. I can’t seem to figure out what is causing my PCV valve to clog (and what other issues it could possibly have) and if anyone had any knowledge on these older JDM engines any help would be appreciated!
