When I start the motor cold, it idles about 800 rpm or so. That is good for me. But when she gets warm, it idles about 2000 rpm or so. I cant turn the idle down cause at cold starts it wont idle or even start without giving it some throttle. BTW a 2000 motor with full bolt ons, a T-REX cam, bla, bla bla, and a mail tune.

Well, after searching this site for all options, I came up with the passenger side breathers on the valve covers, the front one needs to be connected to the top front of the trottle body (I think) and the other can be capped. But I still have the oil fill cap and dont really want to pull the valve cover to remove that for a breather, so is the front one to the throttle body enough of a vent? I do have a vent on the driver side where the pcv was.

Right now, I have the tb port capped and the two small ports on the valve cover just has tube with vents on them. After searching, I think I learned that the front one NEEDS to be connected to the tb, right? Would this create the vacuum leak that would cause the high idle?

Yeah, it would cause it to suffer actually. probably not be higher.

So that will not cause the high idle?

A vacuum leak.

Where?? Now the only vacuum lines being used are the one from the tb to the front of the pass valve cover and the rear of the intake to the th400 tranny. Everything else is capped off. I dont know what else to look for.
