1998 Catera Codes 0161, 0141, 0411, 0140, 0455,
Took my Cat to Autozone and got these codes. Seems like a lot. Anybody have experience with these codes and suggestions on where to start. Thanks!

Codes are meaningless without definitions, and those aren't even cpmete codes. What are the letters on front of them? P? C? B? U?

Secondary air injection pump pressurized your engine every time you start the vehicle and during it's running. If your start your vehicle and it sounds like loud vacuum cleaner working at the same time for few minutes, it's mean your pump open and pumping air not in engine and you have to reseal your pump, if its sounds like vacuum cleaner running but its not loud for a minute or 2, its mean pump working correctly, but check your hoses if they off or broken, if you do not hear any noise you need to check your fuses, check if any voltage going to pump too, otherwise you will need to replace pump. Thread was here on forum not to long ago about same symptoms when air pump went out and guy had all o2 sensors codes
Search for threads!!!!
Of O2 sensors and air pump, read all of them, u can find and solved your issue
