ok, my 99 yukon has 2 trouble codes that come up...

P0141 HO2S Heater Circuit Bank 1 Sensor 2
P0430 TWC System Low Efficiency Bank 2

Now for some reason i was under the impression i could take care of it with my HPtuners software. today i went to see and found out i can't.

I need to resolve these codes for inspection and my 45 day period is just about up so i'll have to go through the full inspection again. but whatever. I really dont feel like throwing new O2 sensors in the truck when that may not be the cure. I see that PCMforless can tune this truck and i was thinking with having them just delete these 2 codes and nothing else. cost would be 125 plus shipping and i figure i'd be done with it. The truck is for sale and i wanna get rid of it soon so doing any type of performance tune is pointless. I just want it inspected.

the p0141 isnt the real issue, that doesnt set off the SES light, but p0430 does. For now, i'm gonna see if i have any spare O2 sensors laying around and i'll try swapping the rear one on bank 2, and hope for the best.

i'm not sure what else to do.
