Fellas it's been so long since I put my ELM on that I don't remember the exact code, just that it was the EGR valve, backed up by a friend's code reader. Didn't give it much thought since I usually just remove those and cap em off. If it's not going to cause issues then I'll just do the same since my state doesn't have emissions checks. I'm not completely acronym illiterate but I'm drawing blanks on PCS and RCM. I'm guessing RCM is a control module which if that's the deal then crap. Those are like $800 for the WS6 and that's cheap American. So again, anything further is appreciated. And thanks for the replies so far.
