I idle up to 3,000 rpms... is this normal after having taken all that apart.. i had to take off the throttle body positioning sensor... is there a special way to twist and put on or does it just go right on?

So I guess is it my TB Positioning sensor or is it normal?

It'* done this twice:
It goes straight to 2,000 then after about 8 seconds it gently increases towards 3,000 (or higher) but I shut it off around 3,000 rpms

I also have a small antifreeze leak between the LIM and my thermostat housing and between the thermostat housing and upper radiator hose. The below gasket (LIM gasket) which i replaced remains leak free. I cleaned off the surface of the Thermostat housing because it had gunk build up. Maybe that'* why?

idle is wayyy too high. you need to adjust the throttle position sensor, im pretty sure thats what u mean by tb pos sens.

do you have a scan tool with live data?

Your TPS is not adjustable. Do you have a check engine light on?

If not, start looking for vacuum leaks.

Well it ended up being the Trottle body positioning sensor. You could either put it on and turn left or right. I turned it right instead of left to line up the screw holes. The spring inside the TB pos. sensor was actually holding the TB open a little, hence high idle.

Other than that, I fixed the leak from the rad. hose to the T-stat housing by scraping off all the gunk from the previous dex-cool.

Still leaking from the LIM to the T-stat housing. So, I am going to go pick up that little rubber gasket.

Those coolant passages were NASTY. Dang.

Did you replace the coolant by-pass elbow? You should, if not. Also, why didn't you use the aluminum frame LIM gaskets?

Yeah I cleaned all the passages out real good, that'* what all those chunks were.

I remember seeing Bill Boost use the orange one... I didn't think anything of it until I put it in...ohhh yeah aren't the aluminum ones like white/grayish looking?

did you dab any RTV in the corners of the gaskets? doesnt look like it.

the aluminum framed gaskets would have been a wiser choice, but those plastic ones are better than what you took out.

there is a lot of coolant sitting around everywhere, did you get that cleaned up before you got it back together? changed your oil yet?
