What do you mean but MY 92 cuz i dont have a manual for it and i dont really know any of my numbers for it. the oxygen sensor is the bosch kind i dont know what it is i just asked for one at Autozone and they gave me the one of my car.

MY 1992 = Model Year 1992. If you have a MY 1992, then you probably don't have an EGR. By the way, what is the trim line of your car? The supercharged engines DID have an EGR, I assumed yours was not.

The Bosch oxygen sensors do not agree with our cars - they tend to make the car run rich and have other problems. If you suspect you are still having problems you need to change the sensor out with an AC/Delco one. Autozone probably has those too.

This is not entirely true of Bosch O2'* & the EGRless 3800. My 92 EGRless ran GREAT with the Bosch O2 Sensor! Maybe it was the extra heat that made it work too????

Don't know if it'* quality control or what...

I've been running Bosch wires for 3+ years with no problems at all. I just checked the resistance on each of them and they are still very low.

well my cars weird the person who had ordered it put a lot of special features in it i probably should get all of the feature numbers off the trunk lid. haynes said something about digital egrs being in years before 1994 then they switched to linear egrs when its not pooring out ill take the firewall off and check but for right now i have no idea. haynes doesnt show much pictures of models over 91. also what does the pvc look like in the 92 bonneville? if somebody could take a pic it would be much appreciative

First off what Model Year & Style do you have????
My 92 SE had EVERY option that could be possibly crammed into it when it was ordered too.

I just bought a 1992 with the "L" in the vin but the build date on the door is 07-92 it seems to run fine should I worry?

So is that why my temp. gauge is over 200 degrees in traffic. Out on the highway it stays between i guess 150-200 degree range. If you know the price of fixing this that would be great.
