hey guys i have 95 lt1, single cat car. i have only 2 o2 sensors. are they easy to do? my car is loosing gas mileage and performence is worse, and passenger side manifold glows even under normal driving. i did plugs/wires. so i think maybe its time for o2 sensors. and help or tips is greatly appreciated.

Fairly easy.
As you said single cat LT1's only have 2 02's, one left one right.

You can buy a 02 socket wrench at Advance Auto or whatever your local auto store is for $5-$10

Just unplug the clip from each sensor, wrench them off and replace. Maybe a PITA if they haven't been changed in a while and are rusted on there pretty good.

Not sure what they mean by that...
Unless you buy a universal 02 sensor that you have to wire into the connector (don't recommend) it's purely plug and go. Wires come attached and wired.

Should take you about 5-10 minutes to do. If you can do the plugs and wires this should be cake walk.

I think Bosch have similar reviews...I've only done AC Delco's personally.
I believe the Pep Boys around here will put a warranty on their 02's...so if you burn them up they will replace them.

Nope. They are just as bad, if not worse. You can use them, but at a risk. Just do a Google search and you'll see what I'm talking about. Even though they are warrantied, who wants to have to go back under the car in 3 months, take them out, bring them back, and put the same shitty O2s right back in?
Delco should be the only substitute.

That looks like a normal LT1 connector to me...
Correct me if I'm wrong but I think the only other connector type for these cares is the rectangular/square one for the LS1's...

Yeah, steer clear of Bosch's. My buddy has gone through 3 in one year ![Bang Head](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_banghead.gif)
Experts I've talked to have always reccomended AcDelco's. I've also been told that Denso's are good if you dont want to spend the money on the Delcos. I know a few people that have had great luck with the Denso's so those may be an alternative to look into.
