Ok, I'm looking for an O2 Sensor for the T-bird. (Its getting lousy mileage, I've replaced the plugs and wires, and cleaned out the Fuel injectors) Summit has these two listed that look identical to me. So which one do I want for the front two ports? (Don't really care if the rear two are bad or not)

Edit: Never mind, I think I got it. Its the NGK-23120

what kind of milage r u getting??? If its not throwing a code then most likely they should be still working correctly.

Well, I may be totally wrong here, but there is a difference in working correctly, and working accurately or efficiently. I've just tried everything I can think of and it doesn't get any better than 20-21 highway and 18 city. I got about 28-30 highway and 22 city with the LE. Pretty much exact set up other than the moonroof. If all else fails I'm pulling the EEC out of the LE and swapping it into the LX! I know, thats just rediculous. But something made it get the mileage it did. And it wasn't because I was so easy on the gas pedal.

Use Motorcraft replacement oxygen sensors only!

You might throw a code soon, if i were you id wait a lil bit longer.

 

[MattsLE97]

i wonder if your bad milage would possibly be from the winter blend gas??? Whats the avg temp down by u that might also be a factor

Oxygen sensor can get slow responding and slightly inaccurate as they age and get carbon-fouled, and they won't throw a code. Usually the oxygen sensors will keep functioning beyond their service interval of 100k miles, but they don't become slow-responding enough to upset the PCM and throw a code. If the things have more than 100k, replace at least both front ones. The rears won't factor into gas mileage. I'll bet you'll see an improvement in power, gas mileage, and overall response of the car.

Thats just what I was thinking. I know its a bad comparison, but kind of like how a spark plug can still "work" but not do it well, causing inefficiency.

you drive 18.8 mph on the freeway? no wonder why everyone keeps hitting your car lol!!

i get about 22mpg with my pi swap/sct tuner...

That's 'cause you drive like a grandma

ok mr 18.8 mph on the freeway

i just dont drive like a wreckless 20 year old thats all

It's not wreckless. I don't swerve all over the freeway. I tend to keep to the #1 and #2 lanes.

 

[Porkchop]

well with a nice suspension/brake setup like yours i would do the same thing.

Anyone know what size o2 socket to use on the o2 sensor?

I have the nkg sensors from summit and they work great.They are the same for front and back and at 36bucks each that's damn cheap
