Unplug it and use the washers to see what happens.

As for the codes, sounds like you have a vacuum leak, exhaust leak, or damaged O2 sensors.

Yep, that's for sure the washer fluid line. I just replaced one on a 2001 Taurus about 4 hours ago.

As for the codes, and the running rough. Here's a few questions for you. Does it smooth out when you raise the RPMs? Is it worse under any particular conditions (engine hot/ cold, driving under load vs free-revving in park/neutral, when it's wet out vs when it's dry out, etc)? See if you can pinpoint any conditions when it gets worse and/or better.

To me, it sounds as if you've got an air leak somewhere, possible a bad intake gasket (common 3.0L OHV problem). It could be a dry rotted/ cracked vacuum line as well.

The circuit issues on the O2 sensor have me concerned though. If it was a vacuum leak, you'd just see the bank 1/2 lean codes without any circuit malfunction codes. Here's some additional info:

A code P0136 may mean that one or more of the following has happened:

* Faulty O2 sensor
* Leak in exhaust close to O2 sensor
* Short to voltage on O2 signal circuit
* Open in circuit resistance caused by corrosion in connector

The P0156 code is the same code, only on a different O2 sensor location. More specifically Bank 2, Sensor 2, meaning the sensor AFTER the catalytic converter. If I'm not mistaken, that car only has 1 after-cat O2 sensor, so I'm not sure why it would be throwing out both banks codes.

Regardless, I would start with the cheapest option, which would be checking all of your vacuum lines for cracks and dry-rotting. Buy a repair manual if you don't have one, that way you can see all of the routing and where all of the lines are. Then, if that's not the culprit, I'd start investigating an intake manifold leak, in which case you're probably better off taking it in.

Good luck! Sorry for the wall-o-text.

Check your PCV line. My Expedition flipped everyone of those codes exactly. I read up and supposidly it was a bad intake gasket, turned out my pcv line was melted through and causing the problem.
