Hi, I am new to the forums and i'm desperate for some expert advice. This seemed to look like the best site in Google... Sorry I kind of feel like i'm just using these forums to get a quick response and even if that is the case. It doesn't mean I'm not here to stay. I appreciate any advice and any responses I get to this post, I am in need of some help and hope somebody here can guide me in the right direction. With that being said, I am just going to copy my post I have on Yahoo answers as i'm not sure if random people on the net are better at knowing Intrepids than dodgeintrepid.net
Good luck diagnosing my problem and thanks again for reading. (sorry so long).
have been noticing some problems with my car. First question is - How many o2 sensors does my car have? O'Reily's used their scan tool and checked my engine light. Shows I am having problems with my o2 sensor(s) and couldn't figure out which one it is. The shop where I had my transmission rebuilt says I have 4 o2 sensors, websites online show I only have 2...
Also would o2 sensors going bad be related to these problems -
Car stalls all the time when I step on gas, have to rev it up to high rpm before it decides to move.
Gas mileage is terrible, would expect better than 20mpg's highway.
Car almost feels like it's going to die when idling, rpm's drop real low then car rev's itself up, repeats process over and over.
Car is shaky sometimes (pretty much same as above problem)
When stepping on accelerate pedal the car doesn't want to go sometimes or have to slowly step on the gas pedal until I reach a point in where it doesn't do it.
Once the car is going it has no problems driving on the highway or once i'm past lets say 10mph.
Could all of these be related to just some o2 sensors being bad, or do I have something else going on with my car? A guy once told me it could me my "throttle positioning sensor"
The car has 120k miles on it, just had its spark plugs done, oil change, all fluids topped off, and a transmission rebuilt.

If o2 sensors can cause all of these problems, I have been told I should only buy the original o2 sensors that came with the car. Can anyone verify if this is true? I would like to buy some cheap ones at the websites I've been visiting for around 35 bucks each. Will a different o2 sensor than the original ones that came with the car affect performance?

Auto Zone Codes
02 (Oxygen sensor)
Circuit condition (heated oxygen sensor bank 2 sensor 1)
The powertrain control module uses the oxygen sensor to calculate the air/fuel ratio in the exhaust
Cylinder misfire detected - random cylinders
Heated oxygen sensor bank 1 sensor 1 high voltage
I know it looks like the answers are right in front of me, but that's several trouble codes that kind of describe what could be the problem. Do these mean we can eliminate the TPS and pinpoint it to the o2 sensors? I'm also a little worried about P0300 with the cylinder misfire detected.
