04 Cobra Idle problems

Can anyone toss out some ideas on this? My 04 cobra started idling bad, almost stalling, then recovering to 1000 RPMS, and will do that after you drive and stop, like to make a turn. Mechanics changed idle air sensor or something (ok, I'm not a mechanic), but it is still doing it. And while driving, if you let off gas and then accelerate again, the transmission seems to grab slightly, like a thump. it wasn't doing that before either. Before replacing the idle air thing it actually stalled at 65 mph while my son was driving it to work (he works at the dealership). Thanks.

There was a reflash for this problem but I thought it was isolated to '03's and didn't effect the '04's. May be wrong. Do you have any mods? Throttle body, pullies, etc.?

The only thing it has is a K&K Filter kit. It was running a little rich on the air when I had it dyno'd in July, but they said it shouldn't bother it if I am not racing, which I don't.

Yup that link is a good one. That should solve the issue. If it dont then you may have some other issues.

you could check the Idle air control (IAC), or the throttle position sensor (TPS) but with the car being so new i dont think those are likely sources
