    I fully disengaged the throttle body clamp to where it is visibly loose and rotates around freely, but the hose will not come off! Any suggestions to get that hose off? I really don't want to pull on it too hard and break something.

    *BTW, all I want to do is to remove the hose so I can see and clean the throttle body - in place - without removing it.

    This is one of the coolant hoses? I'd use the tip of a flat-blade screw driver, push back on the hose edge at one side, then on the other side, as many different points as you can reach. pull on the hose while pushing; it should come off.

    Is this just to remove the throttle body for cleaning? If so, there's enough play on the coolant hoses you can lift off the throttle body, do most anything. Without spilling coolant.

    Throttle body hold-down nut/bolt spec in attached.

    Perhaps there's some fasteners you've yet to see/remove?

    Hose picks often have a good shape for getting in under the end of a hose and lifting it where it has become stuck to the nipple it's attached to—especially as the nipple is often sticking out of some object that gets in the way of a straight approach with a screwdriver or something.

    Hose grip pliers are another approach. They give you a good enough grip on the hose right where it's over the nipple so you can twist the hose till it lets go (without squishing it super tight against the nipple like other pliers would, which would only make it harder to twist free).

    You are talking about the throttle body hose that goes on the throttle body right It's big round two and a half inches 3 in usually squeezing just above where that clamp goes makes the edges of the hose lift up a little when there's access I take a big pair of smooth channel locks and just put it on the hose and twist a little bit You don't have to squeeze to kill the hose You're just trying to make the hose twist a little bit one time then it will pull up this is true of most hoses coolant air rubber doesn't matter.
