RE: 4000 exhaust problems... Help

     You don't really need that CO tap tube to have the car running right 
     (it's only there for diagnostics), but you definitely need the oxygen 
     sensor.  When the computer detects no signal from the sensor, it 
     defaults to a "rich" mode, which makes it run bad, and blow lots of 
     black smoke.  It's meant just to get you home or to the nearest repair 
     shop.  So, have that sensor installed and hooked up correctly, and 
     that should make a lot of difference.
     
     With respect to the water in the exhaust, that shouldn't be a problem, 
     especially if it's when the engine is started cold.  Some steam coming 
     out is normal.

     Hello All, 
     My 4000kcs has small amounts of water(I believe) coming out of the 
     exhaust
     when I drive it-how often I don't know.  In addition to this, there is 
     always
     large amounts of "smoke" coming out of the exhaust.  Also, I don't 
     have an
     oxygen sensor it has been removed, along with the Cap for the CO tap 
     tube,
     and an end cap has been put on the exhaust(in the spot where the 
     missing
     parts should be).  I would like to know how does not having an Ox 
     sensor, and
     tap tube affect the running of my car and/or how might it in the 
     future.  How
     hard is it to install a new tap tube...My inexperienced eyes missed 
     this when
     I purchased the car.  Any answers and suggestions about how I can go 
     about
     solving this would of course be most helpful.    
     Thanks, Chris
