Did they replace the counter weight when they replaced the flywheel with a light weight one?

I would think that it would be VERY obvious if they did not put on a counter weight. If I remember correctly, the counterweight is actually a part of the stock flywheel, so if they just put on a flywheel and no new weight at all the engine would prolly run like crap.
Definitely sounds like a vac leak, or something not plugged in right. Start at the front of your engine bay and check every connector to be sure they are connected correctly and completely. Then follow every vacuum line, making sure they are connected at both ends.

I've had a similar problem with my '04 RX8 twice. But it was caused by 2 different issues.

The first time, I installed a new midpipe. It messed with the readings from the O2 sensor near the catalytic converter. That in turn screwed with my fuel mixture, causing the engine to stall when the RPMs slowed to much. It also idled very rough, and would almost stall while idling. If that does turn out to be an issue for you, it helps to reset the ECU setting to factory. It will help until the computer starts to change the mixture again.

The second time, the car started dying for no apparent reason when I would stop, and I would occasionally notice a flicker in the radio display. After much trial and error, I figured out that I wasn't getting an even flow of power from the battery. My contacts were clean, but not conducting properly. I replaced them with a $5 set of contacts from AutoZone and haven't had an issue since. Since we both have an '04, I suppose it could be worth checking.
