I have a 2005 Toyota Corrola, 122k miles, the "engine check" light came on last week and we took it in for a diagnostic check, they said that it was a "Oxygen sensor" and they "Zeroed" the Engine light and said if it happened again to bring it in.  2 days ago it came on again.  The engine runs fine.  I am ordering the part from the US because I am in Germany for 36$.  It is 150-200Euro in Germany. It will take 2wks to get here.  Is it okay to drive the car in the mean time or should I borrow someone else's because I could "ruin my catalitic converter"?  Thanks,
