Hi All, If you have a 2006 or earlier Jeep, and you wanted to goose the throttle a little to make sure everything is working well under the hood, all you have to do is tug the throttle cable a little where it attaches to the throttle body. Beginning in 2007, all the 3.7’s became drive by wire. Is there a way to do this now from under the hood? The reason I ask is that I’m looking at topping off my AC refrigerant (it’s a bit low but still sorta works) and I am seeing that the rpms have to get up to 2000 or so to read the high side pressure. It will be hard to read the manifold gauge under the hood while sitting in the drivers seat with a foot on the gas. Thanks, Jeepers.
