I am not an auto mechanic, but  I have a strong desire to learn, I look
at this problem as a weekend project (maybe a couple of weekends).
Getting the tools is not a problem. i can always get em from autozone
just the way i loaned the OBD2 reader to get the error code.
The only issue is the know how.... i want to learn about cars and avoid
getting ripped off... more importantly i want to learn something new
and cars is something that i would love to learn.
Money out here is not an issue, i can easily go down to the dealer and
fork out a few hundred dollars and that still wont cause a dent in my
savings.
However, it will definitely cause a dent in my determination and moral,
something that is more valuable to me than money. Money can be earned
over time... but running away from failure the first time will cause me
to run away forever especially knowing that i failed without giving it
a try first.

Btw,
So far i have figured this out to be a problem with the O2 sensor...
there are two O2 sensors in the car, one before and one after the
catalytic converter,
Now i totally understand that i may be that the O2 sensor problem may
have been caused by something else...therefore:
1) I am going to reset the computer and erase the code from it to see
if it appears again.(Several month ago the computer had glitched due to
jump starting my car, it may be that something similar has happened
this time).

2) Locate the sensors,( I have already found where they are located
under the hood).

3) "Learn" how to determine if the sensor has gone bad.

4) Learn to remove the sensor and test it.

5) If it is bad replace it and check again.

6) If it good , do the same set of steps for the other sensor.

7) If the second sensor is good too....take it to a auto mechanic :-)
