PCW valve change?
i was reading some stuff about changing the pcw valve. the ideling on my 2008 suburban is sometimes not steady, do i have to change it or is there already a updated one in there? i am going to get the tranni and oil serviced and i was going to get new spark plugs as well, was just wondering if this should be changed too?
