well my car definetly needs new o2 sensors i got the codes read at autozone and all 4 o2 sensors came up as well as my egr i needed a new egr valve wich was replaced by a stealership and they said that i needed some o2 sensors and my SES lights comes on every now and then and i assume it is the o2 sensors

but is what i wanted to know is there any good right ups on how to replace o2 sensors? i have searched the whole sight and found information about o2 sensors but not a write up on how to replace them.

also how much do a decent set of o2 sensors cost?

thanks

Do you plan on getting long tubes fairly soon? If yes, do a search for Corvette o2 sensors.
If you decide to go with an ORY, you wont need new rear o2 sensors.

Replacing these sensors are easy, if you can turn a wrench and unplug something while the car is on jack stands in the air, you are golden.

Disconnect battery if you want.
Jack the car up.
Place stands underneath car.
Disconnect the sensors you are replacing.
Wrench off old sensors.
Repeat everything but in backwards order.

I'd post all the codes first, all four 02's failing simultaneously sounds like a symptom of something else going on.

Yeah get it scanned at advance auto parts, auto zone and look up the code to tell which one it bad.

just delete the rear o2's and avoid the cost of buying rear o2 sensors

Why would you do that?

Because they are useless?

Yes grasshopper


Instead of using the money to buy the extra 2 02 sensors, use it to tune out the rear 02's, egr, etc

VetteMan

Why did they put them there?

there useless man, they are there only to sense if ur cats are working properly! but if ur cats ever clog (not a big possibility) it will tell u that its clogged, but anybody would know when the cat is clogged so its obvious, u dont need the rear o2's
