needing a little help, I am having that same little idle issue with my 4.6 witch seems to be a big topic with the 4.6, the only check engine light I had was the EGR VALVE code, had the EGR changed and there are no codes to be found, I am hearing a slight rattling noise coming from the PCV VALVE, could that be an indication it is going bad,?? for what I have read that it should be changed every 30,000, I have 200,000 and not sure if it has ever been replaced,!! how do you remove the old one,


thanks
