Well after reading numerous post on the topic I decided to pull my EGR valve out and take a look and clean it. I went to the dealership and got the o-ring kit and a bottle of carb cleaner and went home to start. Well after a couple of hours of pulling turning wiggleing and alot of cussing I still have yet to get the valve out. I put the two bolts back in plugged it back up and said the heck with it I will run the truck till I need a new one I guess. Everything I read said they are a pain to get out but I would have never fathomed it would be this hard any tips would be appreciated.
