Just wanted to point out that without O2 sensor input, the CIS(-E)  
fuel mixture system goes into a limp home mode of sorts with a better- 
safe-then-sorry fuel mixture.  That mixture is on the rich side, not  
lean.  Rich mixtures lead to bad fuel economy, nasty polluting  
exhaust, sooted up pistons and valves...etc.  Lean mixtures can lead  
to a burned valve or valve seat, or even a burned piston.  Factory  
installed logic:  For Your Protection. :)
