Ok, I just got my second accord with less than 95K miles at $1100 below book. It was fine the first day I drove it, but today after a hard accel on wet roads it popped the above two codes. The cat does look a little rusty. I'm taking it a mech next week and I cleared the codes to see if they come back meanwhile. How much should I be worried? :-) I don't
mind putting some work into it since I paid so little. I imagine if I stay off the highway it will be fine for awhile anyways.

122-TPS low input
420 -Cat efficiency below threshold

thanks
