Ok, so I'm new at the whole "doing your own maintenance" thing but I thought I'd take a crack at it. So, changed the spark plugs, no problems. I was checking the pcv valve, and the whole hose came loose. Now I have no idea where it connects to the engine. I have a 4.7l v8 2006 Commander. I would really appreciate any help, because my husband thinks I'm not capable of doing this on my own and thinks I should just take it to the dealer to have them do all the maintenance. I figure, if I've got a Jeep, I should know how to work on it.
