MY idle is wierd, when it's warm sometimes it'll stay at 1000 rpms at idle and if I blip the throttle it'll drop down to 750 and bounce between that and 600 rpms. If I revv it in neutral and let off, it drops down normal and likes to hang a LOT at 1200 or so rpms. It's wierd and it's really bothering me. I've set the TPS, cleaned the EGR, and cleaned the MAF and well that's basically where my knowledge stops. This all started after the 70mm TB, u/d pullies and the blaster TFI install. Help me out guys!

you clean your IAC? Idle Air Control Sensor? Or you could have a small vacuum leak to.

Could be, but I dunno where it would be at, I haven't messed with anything on the intake but the throttle body and egr spacer, maybe I should try and tighten it down a little more?

have you removed your smog crap?

Nope, smog is still operative on the hatch (the one that I'm having issues with now), but I've removed the smog **** on the vert and it's even worse. What would cause that with all of the smog stuff disconnected?

92hatchLX

One more thing, I never reset the computer (disconnected neg. battery cable for 30 minutes) after this stuff was done. Do you think that it would help? Or would the computer have learned all of this new stuff by now? I've probably put 200 miles on it since the modifications.

once you remove the smog stuff your egr will start to go. sometime if you dissconnect the vacuum line on top it will fix idle problems.

You probaly shoud readjust your base idle. dissconnect the negative for 30 minutes along with the IAC, then connect the negative and start it let it run for a minute and set your idle, then turn it off connect the IAC and turn back on and let it idle for a couple minutes.

Try cleaning the IAC as already suggested above.
