Clyde,

 

About 32k miles.  1992.

 

Will try your suggestions -- though probably won't be able to for a couple of 
weeks -- and let you know.

 

Many thanks,

Larry

Once again the warning light has appeared. If there isn't any noticeable 
adverse effect on performance (no missing, unusual sounds, atypical gauge 
readings), am I correct that (1) it's probably a loose wire and (2) no harm 
will probably result from driving it (at least 10 miles to my dealer, or 
another competent mechanic)?
