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.

A direct fit converter for your car is is available from Eastern Catalytic. However a reputable muffler shop should be able to install a threaded port for the 02 sensor if you want to go that route. Call around, get prices, and from that you can make a decision.
Hope this helps.

This is Bank 1 (closer to the dash panel) Sensor 2 (located after the catalytic converter).

Note: A malfunctioning front oxygen sensor may cause fuel trim codes to set.
  1. Several Diagnostic Trouble Codes use specific terminology to refer to sensor location. The illustration and key below explain the following terms:
  2. Engine BANK Bank 1 is closer to the dash panel, (also referred to as RH or right hand). Bank 2 is closer to the radiator, (also referred to as LH or left hand).
  3. UP Refers to Sensor 1 or "front sensor". It is located closer to the exhaust manifold and before the catalytic converter.
  4. DOWN Refers to Sensor 2 or "rear sensor." It is located after the catalytic converter.
  5. The following examples show how to interpret oxygen sensor terminology:
  6. B1/S1 = Bank 1/Sensor 1 = Dash panel side, BEFORE the catalyst or "upstream"
  7. B2/S2 = Bank 2/Sensor 2 = Radiator side, AFTER the catalyst or "downstream"

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.
