High Idle

[BenHooker]

Ok, I just installed a throttle body spacer on my car today. I have an automatic, and when I turn the car on, the RPM's rise up to about 3k and sit there. When I put it in drive, the RPM's lower to about 1.25k but are still higher than normal. I can't figure out what could be the problem. Any ideas?

Do a boost leak test.

How do I do that?

My car was doing that the other day. Thers a set screw on ## throttle body, sorta on the top twords the front of the car. Turn the car on an run the screw in until u reach the idle rpms u desire.

The throttle body cable? No, it's in the right spot. My friend and I both looked over it tonight. Forgot to mention though, when it is in drive there is a hiss, so there is probably a leak somewhere I just don't know where to find it or how to.

It wont be a boost leak since your wishlist states a turbo and the cars a NT. You may have a vacuum leak though. Theck the vacuum lines and make sure the tb is tightened down.

Also, when you adjust the idle scree, does it lower/raise the idle?

Sorry, I'm pretty new to this stuff. What idle screw are you talking about?

 

[3tcpower]

On the throttle body, or around there, there should be a hole (fairly deep) that has a screw in it. I will see if I can find a pic.

Don't worry about it. I fixed it. My spacer was installed upside down.
