07 Boss,
Yep you definitely got your money's worth out of it!
I'm throwing my old catted mid-pipe on for now as I gotta get her running well for smog next week. Ordered a new one. They're pretty inexpensive and that last one lasted about 10 years or $1/mos so I'm not too worried about it. But just for anyone interested, mild untreated steel and it lasted for 10 years in the high desert.
Maybe swap O2 sensors side for side first? See if the lean condition follows the sensor.
This is typical when new O2 sensors are installed & KAM wasn't reset. PCM is using the last O2 sensor testing results of the old B2S1 & the new front O2 sensor's inferred center scale & amplitude range differs (slower) from the old recorded data from the old front sensor enough which caused PCM to think the O2 sensor is bad thus threw the DTC. Since this data has now been updated (and you reset the KAM which clears out all the old Mode 6 data when you erased the DTC) the PCM is starting over w\ a clean slate so you most likely won't see any more of those unless there really is an issue. Sometimes on the initial warmup of the new O2 sensor's element they can be a little slow to respond then afterwards they'll respond just fine.
Oh that's purty!Yeah, that's what I figured. I switched from the Bosch to the NGK 22060's and figured the modulation would be slightly different. I cleared it and it hasn't come back. Car is running like a champ, no codes, and passed my smog yesterday. New O/R pipe came in and had the bung for my gauge welded on. Might be a while before I swap it in and get the cats off of her as my other car is taking up the garage getting new suspension and chassis work done.
Curious, are the cats you're using to pass smog the OEM cats\midpipe w\ the O2 sensor bungs mounted in the middle of the cats?
Would you mind posting a link to those cats so that I can look at them?
