Question

I got the below codes for my 2006 Acura RSX (180k miles.... I know, I know). The maintenance and check engine light is on. And now the AC is out.

P2649
P0420
P0661

I've never had any issues like this before. I keep my maintenance book updated, oil changes every 3 months and mid-grade fuel every fill up. The upkeep has been up to par since buying it back in 06. Obviously the warranty ran out (see miles), so I only go to the dealership for oil changes. Now I'm looking for a way to keep my car.

On a tight budget here. Any help is appreciated!
