Rough idle and low RPMs at startup when cold...

Thank you! Would the fact that it's a straight cat be a possibility too? I may just have to change the idle speed... that would be an easy fix, and a great relief. The previous owner had replaced the AFM, so I'm guessing it has no problems. It's mostly stock. Just a aftermarket radiator, MHG, studs, hoses, seals.

P.S. That site is amazing...

The idle is computer controlled.... screwing with it for the sake of masking a symptom is simply stupid; If you are really running rich you'll still be getting the error code, still be losing power and still be getting worse mileage than normal. Fix it or sell it.

Sorry for the double post, but I let it crank a little longer this morning and the rpms were just fine, so now I'm wondering if its the straight cat? I dont know much about cars, I apologize if I trouble anyone.

What did you mean when you said "gut the honeycomb"? I know there is no cat on my car...is that the same thing? Sorry for my noobness, I appreciate your help.
