Sounds like you have low fuel supply or a leak in intake system causing lean codes, check fuek pressure and volume first. Cat converter effeciancy could be caused by the lean codes, purge system sounds like solenoid failure, check for high resistance accross purge vent solenoid.

Getting a code P0420 on my 2006 V8 Mountaineer

PO420-"Catalyst Efficiency Below Threshold Bank 1".Most likely you have a bad O2 sensor on bank 1(driver's side).There are 2,replace them both to make it easier.(My guess is the sensor before the catalytic converter is the bad one,if you want to try just one.)

I have a 2002 6 cyl Mercury Cougar. I need to replace the o2 sensor... How would I do that?

The o2 sensor is located one top of the air intake pipe. All that you have to do is take the bolts out and unplug the o2 sensor and replace it. I hope my advise helps you.

My 95 cougar(beast)as i call it.will not pass smog.had codes tested and it comes up as (code)0173&0174,bank 1&2?please help?

you sure it's bank 1 and 2 ? they are both for bank 2. either way it's a fuel problem. not getting enough of it.. here's a link to some info but before you even look over this i'd check your MAF sensor and your o2 sensors maybe fuel pump and fuel filter.. this article has a couple pointers.

If you take care of one the other should be corrected too.
