But what I'm seeing sometimes is a drop below 500rpms. About 3-4 times now, it's dropped low enough to make the engine miss a beat and come back. The rest of the time, it's still bad enough that you can feel the engine shaking through the car.
I've had my car in twice now to tell my dealer about it. The first time, they said the car was just trying to save gas and run lean. The second time they hooked it to their scanner and couldn't find anything. And they didn't see any TSBs for the car, either.
I have no power mods done to the car. Actually, this has been holding me back from doing anything to the car. As I don't completely trust it right now, I'd hate to throw some headers and a tune on it only to get a CEL later and have the dealer tell me I've voided my warranty.

Seals, it is possible that the injector seals are bad on it. Usually this is a problem that mostly happens to people who track the car, but I guess enough ambient heat can do the trick as well. Does the car dip to around/below 500 rpm and then right before stalling goes up to like 1k rpm on its own and does this little cycle several times in a row? If so, it might be the injector seals, if it does it only once it might just be the AC that turned on. Remember that when you have the air directed towards the windshield (or feet and windshield) the AC is on all the time, wether you want hot or cold air (its a setting on the car that can be changed by techstream and the default value is on).
