make sure your throttle cable didn't come un-adjusted on the intake manifold. Sometimes they slip.

Spray brake cleaner or carb cleaner on all of your air fittings and hoses. You may have a leak(s).

Ok I read ## thread...I just realized that there isnt a gasket between my throttle body and my air intake...would that help any of this...

I tried this...no leaks

make sure your throttle cable didn't come un-adjusted on the intake manifold. Sometimes they slip.

How do I kno if it came unadjusted? Like what am I looking for?

I'm having the same problem, my idle was sitting at 2500 RPM and a friend suggested I close my FIAV and that brought my idle down to around 900rpm, it took less than an hour, and was very simple to complete. Let me know if you need instructions. Now I just have to figure out how to get it down to 750rpm. Hope this helps

Do you mean between your throttle body and your throttle body elbow ??

That should work just fine. And if that doesn't do the trick, then I would build yourself a boost leak tester (if you don't already have one) and check for leaks and then will go from there.

You need to adjust your throttle cable where your cable and cruise cable go into a box on your passenger firewall. Your cable is most likely pulled tight causing your high idle, dont worry too much about your BISS right now, try adjusting the cable first, I had the same issue, fixed it in 5 min....go to post #3....http://www.dsmtuners.com/forums/maintenance-repairs/373222-throttle-cruise-control-cable-setup.html the last few pics of post 3 shows the box I am talking about, undo the 2 bolts and pop the case off, follow the cable from your throttle body to where it goes into the assembly, loosen the nuts, adjust the cable so it is slightly more slack, retighten the nuts, take a look in your throttle body and make sure your throttle plate is completely closed and opens 100% when throttle is pushed to floor, should fix your problem-Gary
