What up Homies. It's been a while seen I've posted on TGC. I'm still out here in the cut. The Galant is still riding. I'm about to hit 200,000 miles in about 3,000 miles. A/C isn't blowing cold air anymore, but that's not a issue with me.
I need some help. I ran a scan test on my car and have 3 codes.
1. P0431 Warm up Catalyst Efficiency Below Threshold Bank 2
2. P0421 Warm up Catalyst Efficiency Below Threshold Bank 1
3. P0401 Exhaust gas recirculation A Flow Insufficient Detected
I need to pass the smog test by the end of the month. I purchased 2 new 02 sensors and 2 spark plug anti-fouler. I have not installed yet.
To fix the p0421 code I was gonna try this.

I'm kind of stuck on fixing or getting around the other 2 codes. Any input or suggestions I would be grateful
