Yes, the lines are a pain. The two on the bottom of the throttle body are the worst. Also, be very careful taking them off of the thermal switch. Old hard crusty lines can be a pain to remove, and the plastic on the thermal switch also gets brittle with age. Why do I know, I broke my thermal switch. Fortunately a little JB Weld and I was good to go (don't worry, I put the thermal switch in hot water to make sure it still worked. Some of the lines are a real pain to get to. Since I had no digram, I did them one at a time. It made a big difference on how the trooper ran. Many of my old lines were hard and cracked on the ends, and I had some big leaks. I used to get the throttle surge all the time before I replaced the lines. I will have to double check all the lines. Thanks for the help on the digram. I should print it and laminate it and then tape to the bottom of the hood. I was kind of ticked the body shop didn't replace it when they put the new hood on.
