another throttle body mod
ok, in the process of putting in new injectors cause the engine was flooding too fequently.....since the UIM and TB are off i might as well modd the TB and clean the UIM....i dont plan on removing the thermo crap...just because i like my idle...but i do plan on removing the secondary throttle plate....thing is...i read the write up on fc3spro but i dont plan to do that extensive of a modification...so can i just remove the plates..leave in the rotating shaft and call it a day?....
want the car to be up and running asap....so not going to bother with JB weld and NPT fittings and stuff

as long as the throttle plates are set correctly and your BAC is still hooked up, you can totally ditch the thermowax crap and do the full TB mod. I don't see a point to doing just half the mod

Just a note... Your car will not want to stay running upon startup without the thermowax. It will idle fine once it is warmed up, but be prepared to sit there holding the revs manually until it gets warm enough to idle on its own. I am reminded of this now that its getting cold out and I have to sit in the car until it is warm enough to live on its own.

I have removed the secondary plates and the thermowax.
My car will idle very low at start up but it will not die off.
Honestly I have not found any dramatic imporvements since I did it BUT it is MUCH easier to remove the UIM now. No coolant lines or extra throttle linkage to mess with.
If you've removed the BAC(pointless to do so on a daily driven car) then that would be why it won't idle.
-------------------------------------------
Back on topic.
I was in the same boat as you. I wanted to just remove the thermowax.
I sat in my room watching tv and started to remove the thermowax.
After 10 minutes of TV watching/working I removed it. I then just kept going.
It is VERY VERY VERY simple.
The hardest part is tapping the old holes which I did in another 10 minutes.
Then going to the store and buying a NPT pipe plug. I just used a bit of locktite and some RTV to seal the holes.
