Idle Still Weird...
 

After putting my intake on, I had major air leak problems which I found out later was just the TID not really being on the turbo. After it was back on, the idle was like bouncing up and down so I figured it was still leaking some air because it wasn't tightened on. So I tighten it and the idle goes back to normal. After that, a week later it gets bouncy again and just recently I retightened it. I made sure to be positive that it was tightened on as much as it would go. Now it idles better than how it used to bounce because I didn't need to give it gas to keep the car going, but now sometimes it idles like rock solid at 8-900 rpms, and sometimes when I come to a stop it will be shaky. Then the next stop it might go right back to normal. Anyone know what it might be?

TPS possibly. They are know to be garbage. Check to see if it is set correctly and to make sure it is not FUBAR.

Idle system in these cars are as touchy as can be. I would only suggest to be sure no vacuum leaks. You can spray carb cleaner around to see if any change in idle. I would check bac valve for proper function, not only electrically, but make certain the inner seal is not leaking. Also check the air hose to the bac to be sure it's tight. Also check the tps for proper setting after engine hot, with ohms and Mazda checker. Also when checking the tps, run it through it's full range to make sure no spikes or dead spots. Should be able to find it.

Alright i'll try those. Also I noticed whenever i'm accelerationg and really pushing the car, after that is when the idle is best and rock solid. When i'm driving regularly and not pushing it, as well as when I start it sometimes, i'll get a messed up idle.
