well i bought those damn 02's that are so conterversial and guess what i got a bank 1 sensor 1 p0133 which is a slow response code, so what should i do, the pass. side one is doing fine then the other day i cleared it and it hasnt come back so im confused, im not getting any insufficient switching codes and now it isnt on. I have the stockers which never threw one code, but are preety old, and some brand new casper extensions should i put them back in,the element is bigger and sticks further in on the stock ones.

I reused my stock O2's with extentions when I installed my LT's with 49k miles on the car. The only code I'm getting is PO420 (insufficient catalyst performance bank 1). Which is from the smaller cats in the aftermarket Y-pipe. No troubles with the O2 sensors. In your case I would definitely try reinstalling the originals. It can't hurt and it may solve your problem without costing you a dime. Thats always a plus.

Sometimes they are great, sometimes they are not. Their life is usually short though and I only recommend the GM sensors in performance applications. In alot of daily driver applications the Bosch's are great and I'd run them in my wagon anytime.

Like Scoggin said, it's a hit or miss. I've used them in cars that went XX,XXX miles with them, and others took a dump in a matter of a few months.

When I got LTs, my passenger side crapped on me, so I got Bosch Corvette rear sensor. No more extensions needed. My gas mileage is at an all time high now, but the old one was giving bum readings...

my front 02s were getting lazy, so i took my rear 02 sensors and moved them to the front location per my tuner. My car has had the rears up front now since 2007 with 0 CEL codes

I'm looking for some today...was getting codes and misfires. Pulled them last night, and I have AFS 98 in passenger side and AFS 97 in driver. Is there any difference besides the harness length? I've got extensions, so if I bought 2 of the same should it matter? I'm thinking of going with Denso and the 234-0425 is more than $20 cheaper than the 234-0487 for the other side, so I'm considering 2 of the 234-0425's.

Just to clarify for some people, GM's are Denso's now.



I wouldn't put new o2's in with your new longtubes. Sometimes new longtubes can foul o2 sensors. I would re-use your stock GM ones for while to see if anything happens before spending the money on new ones.

OP, do you have HPTuners?

I put Bosch 13111's in my A4 car and the very same day I got the slow response code, so I changed it to No Error Reported in HPTuners and have no problems.

My buddy tried Bosch 13111 and it was codes after a couple of months. My stockers worked out for several months after my LT install, then started throwing codes - at first infrequently, and after time, constantly.

I tried Denso and a Bosch universal. The Denso started throwing codes after month and I tried it on both sides. I couldn't get the Bosch universal to work at all. Waste of money.

I finally gave up and tuned my car to run full-time open loop. It has been working well for several months now.

i just extended the wires on my oem o2s myself... i haven't had any issues or codes thrown so far... i plan to get densos when i get a tune that way i will have fresh o2s in when the tune is done but in the meantime i'll just leave them how they are

Ive had 2 sets of these O2 sensors fail on me thus far. I drive my car maybe 3-4K miles a year. This didnt happen until I had the cam installed.

i dont understand why some cars like them and others dont i took both bosch's back to AZ and got my money back, my 02 extensions finally came in so i put the stockers back in, gas mileage went way up, back to normal i havent checked to see if im throwing codes but my sotp meter seems dead on!

metalmechanic

i had they same problems with mine after install, used same o2 u did, that vette bullshit didnt work either,then installed 2 new ac/delco sensors, reccomended by tuner, GM Tech, works fine now, my motor is stock cept for complete exhaust, he just adjusted timing i believe
