I think one of your coil packs is dropping out. I've heard of that. Drive the car until it does it, pull over and pull coil pack leads off one at a time (replacing it if it DOES make a difference to the idle or even stalls) and when you pull one off that makes no difference what so ever, that coil pack or something to do with that cylinder is stuffed. I'd try the coil pack first though. A second hand one would be about $50 from the right wrecker. A whole set of coils will be about $300 from eBay (yellow jacket coil packs are great value)

Hope this helps.

check your afm, i had the same sort of problem in my 33, the afm was dry jointed. All you do is cut the silastic off the top cover, pull off the metal shielding then touch up the solder joints between the plug input and the cct board. Took my about 15min and fixed it straight away.

When an RB sounds like a WRX it means it is only running on 5 cylinders. Therefore one of your cylinders is not firing.

As has been said above. Disconnect one coilpack at a time, the coilpack that doesn't change the engine note is the one that isn't firing.

i had the same problem, not only check your coil packs, but check your injector plugs. the clip on one of mine was broken so kept falling off. i put it back on, drove 2 minute down the road and it fell off again. worth a check

Agreed. Had the same problem myself. It'll probably be a coil pack. But as Ben said a quick visual of injector plugs as well might show something obvious. But commonly it's a dead coilpack.
