Is there a vacuum detail available from anyone? I need help, I just switched engines in my sons truck and replaced it with another of the same year and model with less miles on it, when I started the replacement the Idol is extremely high, Im sure I have everything in its correct place but the throttle body has 2 places on the side that look like they are in need of a vacuum hose. when I put my finger over one of the tubes it does slow down, so I ran a temporary hose off of this and stuck a bolt in the end but by then it was back to the high idle and since then by placing my finger over the tube it no longer decelerates. Im completly stumped on this issue and trying to figure this out on my own rather to have it taken to a shop. It has to be something Im not looking at, excuse me for my ignorance Im just a parts changer and one of those do it yourself dads to save money.
