   The red light just says I NEED AIR.  The gauge on the pump and on my    
   nifty little talking digital one are never the same -- I've NEVER seen    
   two gauges the same, in fact.  For one reason, you lose a little air    
   each time you check.  I wonder if the sensor device itself has a tiny leak.   
      
   Some of the tires have plastic caps, some not. I had a cap on this one    
   originally, but I lost it a while back.  No difference.  I keep meaning    
   to buy some of the metal ones with the core tool, but I forget.

   Yes.  The others hold air for months with or without cap.

   I'm sure that if the dealer (amazingly enough, and against everything I    
   knew about buying used cars for the last 50 years, I bought the car from   
   the dealer, and it was the first one I drove when I decided on a 2- or    
   3-YO Corolla -- I couldn't see a reason to NOT buy this one!) would have   
   found something obvious if he'd bothered to look.  They used to do a    
   free rotation with the discounted oil change, so there's really no    
   reason he shouldn't have given it a visual inspection;  I didn't expect    
   them to take it off the rim.

       I'm not saying we should kill all the stupid people, I'm just   
       saying let's remove all the warning labels and let the problem   
       sort itself out.
