Consuming to much fuel?

What do you propose for my tires? About the o2 sensors of NTK is the 6384 the correct model for my TJ?
NTK 23159 is what I get for your 2005 with a 2.4L engine. But you're in Greece and I'm in the U.S. so it's hard to know if our two countries have different requirements for smog systems dictating different O2 sensors.

I want to update the topic with my latest findings.

Today I changed my thermosta because I had some heating issues and my O2 sensor as Jerry proposed. I only changed the upper O2 sensor, because my parts dealer was out, so I orderes the lower one.

Even after I got the metrics from the garage and they told me they look great (I have attached a photo in my previous posts) even no check engine light was on. You should see the sensor... I should have a picture of it. Its not only the sensor was burned... the metal was demorphed. There was kind of a metallic bubble on the side.

I don't understand why there was no check engine for that?! I know its working in so many other staff.

I want to change the other one too and get back too you about the consumption

Heads up on the o2 sensors. The first one controls the mixture (thus affecting your mileage) the second one just checks to see if the cat is good, so if you have no Cel it can be ignored.


There must have been a time
when we could have said no.

Thanks for the update, it's much appreciated.

Too bad you don't have a photo, I'd love to see it. From the way it sounds, it really should have been triggering a check engine light!

yes and that troubles me. I ordered an OBD scanner so I can check the status of the car by my self. I should have it in 2-3 days

It's a good idea to have one around. I have one and I use it on all of our vehicles. It has come in handle more times than I can count!
