I have a bit of a problem, if I push in my clutch and the RPM drops bellow 1000 my car stalls, Unless I'm at a full stop and just turned the engine on. A couple of days ago my check engine light came on, I immediately got it checked, codes are for bank one rich and bank 1 threshold. I'm not sure if this has anything to do with the stalling or not.

What's the code?
I'd start by looking at the spark plugs.

Should probably be P0420. It's not really going to cause what you're describing but could be a factor.
Need to know the year your car is, what the mileage is, if you're the original owner, and any modifications you might have.

I have the exact same problem but my check engine light will come on then after driving a few days it will turn off. My car will sometimes run without a problem on some days. I was thinking that since I haven't changed my spark plugs that could be a problem but could this be a O2 sensor problem? 2005, about a 100,000 miles, spoon axel back with a AEM cold air.

Just checked out my code and it was P1034
