Got the co2 to pass, new O2 sensor and new seals for the injectors.  thanks 
for all the input.  However still failing hydro carbons at idle.  So finally 
took the $yncro to the dealer(Dick Hanna Vancouver Wa).  They think it is the 
catalytic converter and will cost $1000 if they do it, or they will take it 
Menicke who will do it for $190.  Why the difference and does this sound like 
the right fix?
