I-Drive was a diabolical setup in the beginning, may need to take it to a dealer to get it fixed/replaced.

Toyota running rich

Do you have check lights on your dash?

If so, have you checked for codes & used
the internet to look them up?

Check fuel pressure with a gauge

You should have O2 Sensor Codes, if it runs rich

The cause may not be the sensor that reports the
condition, unless they have not been changed at around
100,000 miles. They just report the converter gases
to the computer

Any vacuum leaks anywhere,even in the exhaust system
before the converter, will lean out the exhaust gases & the
computer will in turn pulse the injectors longer & you get
what you have.

There are many causes that can take place,a loose
air filter cover,something simple,a failed,dirty or stuck

No --putting something in the gas tank at 12 oz to 15 gallons
of gas, is a waste of time & money

You really need the factory diagnostic manuals, so
you can follow charts etc to get to the issue.

The Haynes books won't be of any value

Is the engine mechanically sound after 10 years or more
It may be using oil & have issues you can't resolve?

Did you buy it used? In that case your guaranteed
that the oil wasn't changed at 4,000 or less & the life
of the engine reduced

Lincoln ls v8 2000 bank 1 sensor 2

Your whole approach is wrong in my opinion & there are too
many people, professionals included, that like sending people
to the auto parts store for something free

The truth is they may give you a code & tell you the car has
a problem,what they don't tell you is the codes you get are not
what is wrong & nothing gets replaced based on a code

Without being hurtful here, you need to educate yourself on how
the OBD2 Systems work & there is more than a lifetime of education
to be had on the internet

So you get a code,now the codes points only to a vehicle system,
one of many & 80% of the time to a component in that system

This is where the problems & expense come in to play

You have to use the codes,then got to charts you don't have,
then component test an item you have no knowledge of what
it does or how it works or how to test

You replace what you were told was a code or part related
& your money is gone & your starting over

Your best choice is a repair shop & then learn as you go &
start doing your own repairs

The O2 Sensor just before or in the inlet to the exhaust
converter is called an upstream sensor
I reports how much oxygen is in the converter
That is then sent to the Computer or PCM in your case
& the computer adjusts the pulsing of the fuel injectors
called pulse width & adjusts fuel trim constantly

The rear or downstream sensors are in the converter outlet
& are also called monitors,which monitor converter efficiency
Basically just sit there for 14 years until the converter is worn out

The front ones get replaced at 100,000 mile or when they
fail if it is sooner then 100,000

The rear monitors never get changed until they fail

My point is ,with no reference material or experience,
& not knowing that no code tells you to replace anything,
your not likely to fix things the first time around

Bank #1 is on the side of the engine that #1 cylinder is on
Pass Side front on a Ford
Bank # 2 the other side

Sensor 1 is upstream
Sensor 2 downstream

You have dual exhaust so you have 2 of each

I personally found an oscilloscope ,which is a professional
tool is the only way to look inside things

An O2 switches voltage constantly
You can see that on a volt meter but not as a graft or sine wave

What is more important is the switching time & that is when
they slow down & need replacement,not wait until you get a code
or they fail
The scope show the time in Milli Seconds & is of value in knowing
how the sensor works.

2005 pt cruiser,2.4 automatic would not shift out of first. codes 0700 & 0733. replaced solenoid pack, speed sensors. did fine till stop & go travel tripped engine light, would not change out of...

You go to a qualified transmission shop and let an experienced technician diagnose and repair the problem. (Unless you can read and understand all the codes from your TCM, and have the equipment to check fluid pressures at all the test ports)
Resetting the check engine light is obviously not correcting the problem - it comes back as soon as you get into stop and go traffic. Your transmission is going into limp mode, which is what it's supposed to do. Just enough to allow you to get it to a shop and get it repaired. Continuing to drive it this way may do further damage to the transmission. What may now be a fairly inexpensive fix (sensor, solenoid, etc), may become a very expensive fix.

Can i get trouble codes without the scanner on a 2004 pontiac montana

Sorry, No. But, here is the good news, take your car to your local auto parts store. They will read the codes for you, for free. If you have an Autozone, Advance, or an O'Reilly's close by, Go in and ask them to read your codes. They do this for free as a service to try and get your business. But the law states they can not clear the codes. Only advise you as to what may fix it.
