Hey, I have a 1991 Camaro and I went to replace my oxygen sensor due to code whatever it is repeatedly showing up. I went to my local parts store and told them I needed an 02 sensor for my 1991 305-5.0L

*been in the parts store 30 times in the last week and they still don't remember me and my car, but besides the point*

Well I went home installed the new sensor, wow did that old one have a build up of carbon. I finished up, cleaned up everything and was looking over my receipt when I realized they gave me an oxygen sensor for a 1991 350-5.7L !

Will this really matter at all? I'm just curious because if it won't work right then I will want to exchange it for the proper one, but if it doesn't matter then I won't even bother with the hassle of removing, exchanging, and reinstalling a proper sensor.

Thanks !

you should be fine. its just a sensor. the computer is what computes the info the sensor picks up.

 

It won't matter.

All the O2 sensor reads is the amount of Oxygen in the exhaust. It then sends out a voltage signal to the ECM telling it what the A/F ratio is.

The target A/F ratio is 14.7:1. This is true for a 2.2L 4 banger, as well as the 8100 V-8. That's the only reason for the O2 sensor (in our cars with the OBD I system).

 

I know they can be frustrating, but in defence of the part counter staff, even though you have been there frequently, they must get 30 parts requests and different makes/models/engines every hour. Over the span of that week that you've been there 30 times, they've probably had to deal with over 3,000 different inquiries (per employee). Expecting them to remember your specific profile may not be realistic. I frequently have to ask people posting questions what the model/make/year/engine/transmission they have, since all those factors can affect either the diagnosis of even what parts and components are involved. I guess I'm as ignorant as a parts counter person, since I can't remember the details of all 24,000 members' cars...

If you want the right parts with the minimum amount of frustration and delay, it would be in your best interest to make sure the dude on the other end of the phone or dudette on other side of the counter knows exactly what they are dealing with. Just trying to save you a little frustration.

 

LOLOL

 

sad thing is i knew the other guy on the end of the counter... and that was my third time that day in there, and for a town or 7000 people with 5 auto parts stores they usually are overly swamped... he must of just been having a rough day cause i walked in and he said hey there mr. vetter what does your car need now ?? the parts and service centers around here sure do know me well..
