OBD I codes

Hey guys, I'm sorry to have these codes posted in another thread on StangNet, I'm usually not one to double post but because I am about to take a 3 hour car trip, its urgent I get some feedback from you guys ASAP:

These are the codes that I pulled:

Code 565 - "Canister purge circuit failure" [X2]
Code 172 - "Heated O2 sensor indicates lean condition on right side" [X2]
Code 175 - "Heated O2 sensor unable to switch, left side" [X2]
Code 171 - "Heated O2 sensor unable to switch, right side"
Code 176 - "Heated O2 sensor indicates lean condition, left side" [X2]
Code 181 - "Adaptive fuel rich limit reached at part throttle, right side" [X2]
Code 189 - "Adaptive fuel rich limit reached, left side" [X2]


I cleared the codes after reading the ones I posted above and during a second test the only code that stil remains s the "Canister purge circuit failure".

Any info on these would be greatly appreciated!

Thanks,

-Will

Cleaned the MAF sensor, eh? Sounds like a plan. I already reset the computer and none have come back so far except for the 565.

The canister purge circuit failure has been a repeating error. Still trying to figure out what thats about :-\
