Does anyone know where I can get Auto Tap so I can try to find out what is wrong with my car.

This is my problem if anyone has any ideas or suggestions.

About a month ago my car started bucking in the upper RPM's like i had bad fuel in it. I thought nothing of it. I ran the tank out and put knew fuel in and my car was still bucking in the upper RPM's. So I changed my plugs and wires because they where getting old and I thought that they could be the problem. After I changed my plugs and wires I still had the same problem. I then changed my fuel filter thinking that could be the problem but that did nothing either. I then pulled my plugs again and they all look good but my car looks like it is running lean now. Now my car is gettng a lot worse. My car is bucking at all RPM's. Last night I was driving home from the car wash and my car did not want to idle. When I got my car moving my car did not want to respond to the gas pedal. I would push the gas pedal and it did not want to go and then it would go and then it would not go. The whole way home my car was bucking very badly. My friend was following me home and said I had a lot of black smoke coming from my exhaust. I managed to get home and then I checked my fuel pressure which is also good. So now my only car does not work and I have no clue how to fix it. If any one has any suggestions please let me know.

Thanks and sorry for the long post.

SES light on?

Nope, I am not throwing any codes.

My car started to do that and it threw an 02 sensor code. Have not changed it, its been sitting this past week.

I just scanned my car with Auto Tap. I do not have any SES lights, but the codes that Auto Tap are showing are:
H P0172
H P0175
H P1153
H P0172
H P0175
P P1153
Are these all symptoms of having a bad 02 sensor or is it something else.

Fuel system rich codes for both banks and insufficient switching for bank 2, sounds like your 02's are bad.

Your SES should be on. Does it come on with just the key on but the engine not running?

When the car is off and the key is on I have a SES light. 5But I thought that was normal.

Yes it is normal. I was just checking that the bulb was working. I would think with those codes set, you should have a SES on with the engine running? If you clear them with A-tap, do they come back? If you know how to log with A-tap, look at the O2s and make sure they are switching high/low when in closed loop.
