So I replaced my upstream o2 sensor, here's the tip of the old one.




Think this may have been the cause of me getting 10-15mpg? lol That black **** is thick, too, you can't even fully tell how bad it is from the picture.

 

No.. i dont see ANY black stuff......wait a se.. HOOOOLLLY ****!

 

as expected. thats usually the source of bad gas mileage.

glad we could help

Haha, look at the resin that fell off of it when you put it down.

 

I wonder what the sensor inside that housing looks. I wonder if you can even see it anymore, lol.

 

What sensor? Thats just a bunch of exhaust particles holding hands.

 

haha...yeah, I'm gonna send that into Guinness.

That is what happens when some dumbass puts an intake hose with two openings on a car and only covers one with an air filter, then drives it for god knows how long.

 

LOL thats not what causes it

 

Oh? I thought all the unfiltered air my car had been sucking in was what had caused the sensor to go bad? Either way, I reset the ECU after putting in the new sensor and so far my mileage does seem to be a lot better, I haven't driven a lot so I'll find out more tonight. I'm expecting my mileage to nearly double, because I was only getting 200-225 miles to a tank.

 

lol, nope not even almost.
