Car is Idling at 2400rpm!
#11
If you follow Xviper's instructions / the helms manuel instructions the bleed job should be fine. Once your done run the engine for a bit and keep topping off the engine coolent in the little resivour(sp -- I suck at spelling); do this for the next few days and your golden. The system bleeds itself really.

Race Miata, where exactly is the coolant line that goes to the cold idle valve? Is it the hose that is on the side of the intake manifold behind the throttle body by the driver's side fender? I was feeling those hoses and they didn't feel too hot, but it may have been because the car was only idling. When I installed the turbo basically all I did was take the coolant line that goes from the head to under the throttle body, and I cut it and ran a loop that goes through the turbo and back to the head so a line isn't crossed.
I'm not sure if I understand your description about your hose routing for the turbo. Are you saying that you bypassed the throttle body? Or did you insert the turbo in series with the coolant path which was once flowing from the head to the throttle body? When stock, coolant flow thru' the TB is in series with the IAC valve. If you bypassed TB, you most likely bypassed IAC as well. If not, double-check that coolant path is not reversed thru' the IAC. Coolant-controlled valve can react dramatically different with reverse coolant flow.

Next I will check the vac lines for a leak, but my boost gauge looks fine around 22 inHg when the car is idling and I don't hear a leak so I doubt that is the problem.
Since this fast idle doesn't happen all the time, I assume any potential vacuum leak in this case is leading to some control valve where it doesn't open the flow all the time.

I just took a look at the Helms Manual. The IAC valve (which double-duty as cold fast idle valve) sits on the side of the manifold behind the throttle body. You should see the 2 hoses going into and out of the valve.

The 22inHg is when the car is idling at 1,000rpm. What is strange is that once the car starts idling at 2400 it will stay there until the car is shut off. I'm confused about the whole thing.

I just bled the coolant system again, and I just noticed a leak at my PCV valve. I have a slight hissing noise that is coming from it. I am going to get a new one from Honda in a few minutes and swap that out. If that doesn't work then I will go get a new IAC and swap that out.

I just swapped the PCV valve out, and although it stopped the hissing, it still idles at 2400 when I drive the car for a few minutes. Time to get an IAC to swap out now.
Race Miata, I know that you asked me before how the coolant lines felt that are going into the IAC and they are very HOT after a short drive, they are suppose to be like that right?

The coolant lines to and away from the IAC valve should be hot after fully warmed up.
Does the EMS control the IAC?
