ok last night i removed the secondary plates from my TB and i noticed a real nice increase in throttle response but when i listened to my engine idle it sounded like it was misfiring. i would hear like little pops ever few seconds. the car used to do this when it was warming up but then would stop once it warmed up and now it does it all the time. what would cause this? Also i'm not sure if this is normal or not but my car idles at like 2100rpm and slowly as it warms up goes down and then stayes at a 1000rpm idle. Is there anything wrong with that alos or is it normal?

 

You probably have a small vac leak.

(I have a big/intermittant vac leak)
Some day I may actually find it.

In the sound clip in my sig, you can hear it idle at 7-800 when I first start it. After I blip the throttle, it idles at 1000..

 

cold my 89 starts and idles at about 1900, when it warms up it sits steadily at 750

 

Any car will kick the motor up to high idle when it's cold.

 

But wait - there's more:
The engine was already warmed up when I started it.
Sorry about the incomplete info..

 

Sounds like a sticking throttle.
