2003 Toyota Corolla >110,000 miles high idle

Wow.
so out of curiosity, while in Wal Mart ( yes shoot me . Walmart) I went to the automotive section to see how much THEY charge for oil change.

my head hit the floor.

45.00

And this is for 'high mileage' vehicles. Meaning vehicles over 50,000.
Um . Since when was that considered high mileage? You mean people dont own their cars that long anymore? What gives? What is this 'high mileage' maintenance stuff and when does it apply to a vehicle?
At 50,000 to me a car is still new/ish. At 100,000 you need to be buying reliability instead of looks.
At 200,000 you need to be buying based on repair you can afford.
I put the 200,000 at high mileage and question the 100,000.
Yes? No?
or does my 110 qualify for high mileage?

Walmart buys lots of folks new engines and stuff.


(they have legal look at everything)


it's kinda like the lottery and all that...

45 bucks for an oil change?

Thats not winning a thing..

gotta pay to play...

not THAT much.
>snort

if you change your own, you getta see what kinda trouble comes out the pan.


girls...

if you check it regularly, watch your dip stick you can tell whats going on too

granted.........NOT as well.

But then thats why you take a wooden stick of some kind ( popsicle chop stick.. etc) and put THAT in there. When you pull it out, it absorbs some of the stuff and you get a better viewing sample

I lean to the lazy for changing my oil


but i changed my oxygen sensor and problem solved

it got a little worse even with a few oil changes right on top of each other ( only waiting about 2 weeks between) to help clear out gunk. It started to 'cough' a bit while driving.

I borrowed the diagnostic from Auto zone and it read the problem in Bay 1 or batch1 or.. something like that.. I dont remember the exact where but it was only reading oxygen sensor and catalytic converter. I dont believe the converter is the problem. And changing the sensor is much easier and cheaper. Even if it was not broken, hey, its 120,000 miles old. might as well.

and.. so far so fixed

well done shewolf.
Change oil every 5000 - 7000 miles. Anybody can correct me there if i'm wrong cause i work in kilometers

no. you are spot on.
and i do.
though there have been times that I changed it close to 10,000 but not very often. Generally every 7 . my car does not require the 3,000 change which I am thankful for.

though i think i will reset my time to about 5,000 now because it was gunky that one time...

i think the 2003 corolla has 2 O2 sensors. I'm not really sure about that so I prolly should shut up.
You appear to have solved the problem anyhow so not to worry.

well, if i can explain it.. with out pictures..

There was only one source, and one wire. It is close to the firewall on the driver side.
I removed the wire, un screwed the sensor, used the spray cleaner, ran the engine.. got all the black smoke out, then put in the new one.
In the housing there was no sign of another one. At least .. from what I know they look like that is!

I see one.. but not two?

If there was a second one, where would it be?

This one was allll the way to the back of the engine. You have to lean in to the driver side of the car and look down about half way right near the firewall..

just not sure thats the correct yaer/ model

Ok. i was gonna remark that something was backwards.

Where the image for the main oxygen sensor is push that straight back and cloes to the firewall.

sub sensor.. I did not know about that one. I see a reference to it in the diagram. i will ask about that and see if that one is necessary to change as well

cloes = close

i should research properly.
does this look like it?
