Been a while.. but Q is spot on with the pressure pointers he gave you. As far as the idle, it kept being a bit too high. I have one of the newer YJs and it does have an adjuster screw on the tb gate. After i checked all the vacuum hoses, replaced the rubber elbows and fixed the pressure, i had no other option but to adjust the tb screw and the idle came down.
