I know that my har has o2 sensors. That's not my point of argument. Its just that well, I don't know

I'll get to ask my mechanic again. I'll also ask him about the seafoam stuff.

I haven't filled up a tank fully forever. I fill it up to 1/2 because if I see the needle at below 1/2 then I don't push it as much.

Yeah, here in Macon - where I am living for college - they don't require emissions inspections at all....if they did, they would lose half of their residents. There are some really bad cars, I feel bad for the environment here! Hmm...swapping vins to pass emissions - sounds highly illegal

Yeah, of course your car has o2 sensors...I was just saying that if you got an emissions inspection done on it recently - it would have showed up if the o2 sensors were malfunctioning. Since it hasn't had one for 9 months or so, it's possible that they've failed. I dont' know much about the Lexus reliability as far as o2 sensors go, but I know that in the Z, they fail a lot...or so I've read.

Wow...if I didn't fill up all the way every time, I'd be at the gas station too much. I've been putting lots of miles on the car lately, over 7k miles since December! These gas prices are killing me....

Well, anything can be working one day and not workign the next day. I was just saying that besides poor gas mileage, I'm not seeing any symptoms of a bad o2.

My school is only like a mile away. I drive like 3-4 miles a day

I agree. It is possible that something messed up. I'd say take it to the mechanic...and if they can't fix it...take it to someone else who can, like an expert. That's what I always did with the Z. My hometown mechanic couldn't always diagnose the problems with it like they could at Z car Atl....it's all about experience with certain cars.

Yeah, my school is about 4 miles from my house, too. So I drive about 8 miles everyday. However, my daughter is currently about 80 miles away and my mom's house where I take her is about 20 more miles from there, so, needless to say, I drive a lot on the weekends....back and forth, back and forth, then back to Macon. It's crazy.....

its probably as old as the car is they can fail gradually but maybe it just fail to a "limit" the ecu thought was unacceptible and thats creating a rich condition in the motor now but the o2 sensor is heading south the ecu can't see the rich condition so it thinks everything is perfect. is there black nasty ness in the inside of the exhuast pipe? this happens to most cars over time if u whipe it off and it forms back quickly its defiantly running rich.

Ever thought of using another mechanic ?

Yeh... if my mechanic doesn't do anything, then my grandpa has a mechanic

My mom lives 37 miles away from me. All the more reason not to see her

I don't see a nasty mess in the exhaust. But if I wipe it a bit, then of course I'll get some residue.

Yes... my grandpa has one. But he's farther away. And my mechanic does more things, like painting (and frame mending IIRC).

hehe no no i mean whipe it decently clean then see how long it takes to be dirty again. new cars take several years to get that dirtiness in the exhuast.

unless they are turbo from the factory they run rich for safety.
