I'm getting some graduation money since graduation is soon here, and i'm wondering if my o2 sensor needs to be replaced....

a while back, when my guage was on 1/4 tank full, i had about 330 miles on the trip meter, now i get about 270

i did put my finger down the exhaust tip yesterday, and came out with this



time to replace? it'* never been replaced after 112,000 miles

Optional. Pull your o2 and see how crappy it looks. you can clean itwith a propane torch for a short term fix sometimes. Why does that pic look like it'* infra red?

112K on the car the O2 is prolly soon to be on it'* way out the door.

I wish I could get 330 miles and still be at a 1/4 tank.

I hit 330 and I'm prolly pushing the damned thing into the gas station.

I would say it'* time for a new one,, and go with a AC Delco one when you do!!!!!!!!

its my camera phone.....its not very good

that gotta be all highway numbers.

i drive 24 miles of highway and about a mile of streets every day

is there anything i need to be careful of when taking out the o2 sensor?

You do not need to buy the special tool if you are replacing it.
Snip the wires and use a deepwell, or if its pesky, a 14in pipe wrench will make it behave.
Just use a box end wrench to install it.

You also might want to check you fuel pressures before doing the o2, running rich would kill a new o2 fairly quick.
