2000 Celica GT-S oxygen sensor help? - Toyota Nation Forum : Toyota Car and Truck Forums

I have a 2000 Toyota Celica GT-S.

When ever it is idleing and i hit the gas it bogs like its going to stall but then revs up. Difficult to get out of first because of the bog might stall it. Does anyone know what this could be?

My check engine light came on and it said rich fuel as well as oxygen sensor.
Do u guys think that an oxygen sensor would cause this because their are 2 and are expensive if i change it and turns out not to be the prob.

Thanx

get it scanned

I got a scan and it read rich fuel as well as oxygen sensor, but didnt want to change it and it doesnt work because the oxygen sensor is expensive.

are the oxygen sensors same for GT AND GT-S models?

Well if anyone wanted to know what i did i replaced the O2 sensor and did not work.
I then took off the MAF sensor and she ran smooth, so if anyone has the same problem as i did check and clean the MAF sensor first and you will prob. save some money.

reason why I said get it scanned was to look for things like the MAF reading wrong and the CTS reading an odd temp and things like that

My 2000 Celica's check engine light is on and it stalls when my car just idles.. sometimes in reverse it dies completely. When I take off from a complete stop it stalls to where I have to put it into neutral and rev the engine then slide the gear to drive just for my car to go and when I stop it sputters and acts like it is going to die. Are the problems that I am having with my automatic Celica about the same that you had with your GT-S??

also.. I took it to AutoZone and they ran a scan on it and they said it was misfiring in cylinder 4 and random misfiring in misc. cylinders.

im not a 100% sure if its the same prob as i had, but take out the map sensor and clean it out with carb cleaner and use a qtip have to get it in the light to see the crud built up. try that can be a quick cheap fix.

Thanks!! I will definitely try that.. I have a friend coming over day after tomorrow to change my fuel filter and MAF so hopefully that fixes my problem. I do know there was some engine problem that Toyota knew about with the 2000 Celicas so I am wondering if that is it also.. earlier when I was looking it said something about the fuel injectors and the computer having a problem or something.. I will find the link where I found that.. it was in another forum so it may not be completely true..

put some fuel injector cleaner in your gas tank and see if it makes any difference at all, your injectors may be leaking or super clogged up. and the MAF would be a good bet too.

I already did the fuel injector cleaner a couple months ago. I generally do that every time I get an oil change and it didn't help. I have had problems since I got the car with the exhaust or something making a rattling sound when I accellerate[sp?].

if anyone was wondering what i found out about my car.... apparently the previous owner tried to fix some problem with the car and pulled some of the emissions things out and caused the computer to read the air intake at below 20 degrees so the place i have my car at had to the part to [hopefully] fix it.. so hopefully whatever part they ordered will do the trick.. so far the repair cost is up to $300 that i don't have..

bobbyex · 03-26-2008, 11:33 PM

is that illegal where you're from? where i am it is illegal to remove emissions components from your car.

Oh wow, I've got a 2000 celica also and I noticed this same dang rattling sound about 6 months ago, it's starting to get worse, any idea what that sound is? I had one guy look at it and said he didn't hear anything, whatEVER b/c it's so obvious when you accelerate!!!

I also have the o2 sensor code thingy reading out when I had Auto Zone plug me up to their code reader so I've got to have some work done on mine too. I guess basically I need to start out with having the O2 sensor replaced and then go from there?
