how to remove 02 sensors on lt1? 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.

NGKs are hands down the WORST O2s you can buy. They have AWFUL reliability and a proven failure record. Do yourself a favor and pay for the AC Delcos, or else there's a good chance you're going to be buying them again in a few months.

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.

k i will prob do acdelco then. quick quetion, when looking at the pic of the ntk sensor, why do they look alot different from stock o2 sensors. heres a link to summit for it check it out. http://www.summitracing.com/parts/NGK-21006/?rtype=10
Those numbers you are referring to are probably the plug wires. Their number come form which cylinder they are hooked up too.
Yeah, steer clear of Bosch's. My buddy has gone through 3 in one year 
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.
