No O2 Sensors??

1257 Views 9 Replies 3 Participants Last post by  Danny
so i have ordered the hedman headers and flowmaster three chamber suv muffler for my 92RRC. i climbed under the truck a minute ago just to see how difficult it would be to replace these parts. that is when i noticed the y-pipe coming from the stock manifold does not have cats and does not have O2 sensors. i search beyond the giant stock muffler at the center of my classic, and still....no O2 sensors anywhere.

did the uk models not come with cats or O2 sensors?? what is the result if there are no O2 sensors?

It did not come with O2 sensors. Not until the P38.
Maybe not in all territories, but mine has them.

Did you fit the LPG system? If it is a close loop system they would have been fitted to control the LPG.
I didn't - it was already fitted when I bought it. It's theoretically a closed loop system with single point injection, but it was a bit problematic so I had the electronically controlled mixer taken out and it now has a manual one. In theory this isn't ideal, but actually works just fine and I don't worry about it. The only 'problem' is that it won't pass an emissions inspection on LPG, so I just switch it to petrol for the test and it's fine.
