I noticed you guys don't like Bosch O2's... Last time I was in the States I bought a set at Autozone.
What's the major problem with them? What are you suggesting, what price?
Thanks in advance!

 

I bought a set, but after hearing all the negatives, I took them back and got the AC delcos since that's what our cars come with. The price wasn't much different either.

 

I put a Bosch 02 in my Jeep, and now it seems to run VERY rich! If anyone has any info on these 02's let us know

 

As far as I can remember, I paid $58 per side. I hope the AC Delcos are a bit cheaper...

 

That's the point! I'm having the same problem, I get a lot of carbon build up...
Please let the inputs coming guys!

 

the delcos were somewhere in the $50 price range, i guess its where you can find the cheapest place.

I was running way too rich before I replaced mine (constang backfire through my true duals) and now its leaned back down alot so there's a good chance they will help cure your rich problem

 

Guys,
I looked up the AC Delco's part numbers, so here it is if you need them:
1994-1997 oxygen sensor ACDelco #AFS75
p/n #25312184
gmpartsdirect.com price $34.07
I guess I'll order them next week...

 

thats a good price, i didnt want to wait so i just went to the local dealer which cost more

 

i remember reading something about the Bosch not being properly matched to our PCM's

im having probs with bosch also......exchanging for ac delcos as soon as they come in stock.

 

I've had nothing but problems with the Bosch o2's. I went though 4 this year and now got the A/C Delco ones and no issue's at all so far. My car would go from running nomral to running way to rich to the point of fouling the plugs and getting misfires.

 

I tried Bosch 02's, and the moment I got them in, LT1 Scanmaster started reading knock retard for no readily available reason at idle. I swapped back in my bad 02's, still ran like *** but no knock retard. I got a new set of Bosch's, still did it. Took them back, and went to the dealer to get some new AC Delco 02's, I haven't had a problem since.

 

Guys,
I'm shocked reading all these posts. I was running stock O2's when I switched to Bosch's two years ago. Crap...I thought Bosch was a good brand

 

If you been running for 2 years you must of not had any problems.
I just bought Bosch O2s and extended the wires on em. I may have problems and maybe not we will see. I may just run em in my ghetto exhaust and then go to Delcos when I get my true duals done.

 

This is why I often do a quick search here before buying even the simple parts. It's best to learn from others' mistakes and there are some pretty smart cookies here

I know I've mentioned this very subject a few times in the past

There are also AFS90 sensors, but that may be for obd2, where there are 4 sensors to cover.
