Check RockAuto.com for your brake rotor. Some of their parts are stupid cheap, and they're here in Houston. Angel and I bought the last 2 brand new brake master cylinders that they had up there for $26 each last week.

I will...
At 100-200 RPM your engine is not running. Hell, the starter turns the engine over ~250 RPM! And I believe the trailing coil cuts off below 700 so your tach couldn't show 200 rpm even if it wanted. Please take a closer look and let us know what it's really idling at. 700-1000 should be just fine.

I remember you saying that and I thought I had said something about it before. 200 RPM isn't technically shown on the stock gauge.
You can see in this pic that if the car was idling at 200 RPM the needle would be pointing at the 0. I'm assuming that you're looking at your gauge and the needle is pointing to the small tic mark 2 spots above the first half-size mark? That first half-size mark is 500 RPM, so 2 tics above it would be 700 rpm (3 tic marks below the 1000 RPM line). That is on the low end for idle, but as long as she doesn't die at stop signs you should be ok.
I may be incorrect on the trailing coil shutting off below 700 rpm, but that is how it acts on my car. I can't remember if that is a coil thing, or a MegaSquirt thing...but I do know when my RPM drops below 700 my RPM gauge will show 0 due to the trailing coil shutting off completely.

doesn't look like that at all. It doesn't have the half-size tic marks. Just the big ones at the 1,000 interval and 5 little ticks in between those. (Also it has darker ticks at the 1500, 2500, ect. intervals as well) After looking at my tack again it is more like 200-400 rpm. I have the video but I can't post it right now cause my computer is in scan mode cause it caught a virus. I will post it later on youtube and put the link here so you guys can see. it is like 7:31 long lol

Anyway, if you're idling below the 500 rpm mark then it's too low. Adjust your idle to be between 700-1000 rpm.
Done.

Any1......
Know where the Faster Idle Adjust Screw is located? I know it is on the throttle body but where? I was looking in the FSM and the diagrams they have are way to confusing to find. Can any1 take a picture of it and virtually circle it using photo shop? I searched on the forum but people just talk about it and there are no pictures of its actual location. I asked John but the screw I was moving was not it. lol
Scott or Chuck you guy know where it is at by any chance John said you might know?

looks really nice man.
i don't know but that seems like you might need to clean the throtle body, just go to auto zone and get one; all you have to do is just take off the throtle and clean it or you can spray some while the car is running.
or as hector said it might be a vac line off or something

auto zone
go get a throttle body cleaner from auto zone! and just take off the damn thing and clean it, or you can spry some of that while the car is running but u'll need some one to keep his foot on gas pedal cause the car is gone die on u like that; either ways u choose.

Time....
....to start getting my Eva back to the meets i just got paid and plan on going to Johnathan's house to pick up a rear S5 N/A rear brake rotor and see where that puts me. I am pretty sure that isn't the cause of the loud destructive noise but u never know. And I can't rule it out until the defective rotor with a giant hole in it is taken care of.
When I replace the rotor I will post my finding on here I will keep everyone posted.

RX-7s are reliable.
It is a bad 1/2 shaft now cause when the car is off in neutral you can hear a scraping noise as you push it along coming from the rear passenger wheel close to where the car got hit in the accident. I have a T2 Differential and 1/2 shafts but that means I will need a custom drive shaft to drive the car around anytime soon. I made a video of the noise and showed it to Pat and he thinks it is a transmission bearing.
I want to take the drive shaft off then push the car and see if I still hear the scarping sound that way it won't rotate the transmission so I can separate the noise to better figure out what the problem is. Would a bad transmission bearing make the same noise as a bad Front diff mount?

Friend told me I should look at this thread as I may have an answer. (sorry for raising a potentially dead thread) Might this be the adjusting screw you are looking for?
Series 5 TPS so it's got two plungers instead of the 1 used for the S4. It's on the side of the throttle body opposite from where the throttle cable connects.
Sorry, if its not very clear; I barely managed to get a half positive answer on this myself (I suspect you are much further along in your mechanical knowledge than I
).
And once again sorry if I raised a dead thread.
