what do all these codes have in common?
Hi
I'm getting codes P0441, P0446, P0456, P0420 and P0430.
I have no cats in the car. My fuel consumption in town is around 12 mpg, so a bit higher than what others report. The cats were removed because they were in bad condition. I suspect excess fuel was sent to the cats. That would also explsin the bad mpg (?)
Any thoughts?

Thank you RCsGX. Any idea what would damage the cats? Bad fuel? Lead? Where I live I have no idea of the quality of fuel going into the tank. Everyone says it's pretty bad. I'm thinking of putting new cats in. But i don't want to have the same problem again. I'm having the fuel system checked soon. Tank, hoses etc

How can I test the air/fuel sensor?
I get really bad performance when driving from A to B if they are at very different altitudes. I'm talking about not being able to rev past 2 or 3 thousand rpm!
I have suspected the air/fuel sensor before. Is it the one just behind the air filter?
