While it was in the shop they replaced the starter as well. Here's the problem, car starts fine, idles at 1,000-2,000RPM's upon start for the first minute, then idles at 500RPM's. After about 5 mintues of driving, everytime you stop the car the engine dies. Starts back up just fine though. The dealership told me that the flywheel I ordered (13lbs.) is way to light for my engine and that is why the engine dies at every stop...This is a huge annoyance and I do not believe that this could be the problem, I've called 3 renowned Mazda tuning shops and they all said the flywheel being the problem is impossible. I also called 3 other import tuning shops and they said the exact same thing. I even called ACT and they said, their flywheel can't be the problem of the engine dying. Could somebody please help me out with this?

Never seen a stealer ship ever put any thing on a car except stock OEM parts period. Don't believe it.
