Re: thanks and one more question

Could be just the normal build-up of "varnish" which eventually causes
the injector spray patterns to deteriorate.  Try running a few tanks
of Chevron gas or add the Chevron fuel additive (Pro-Guard???) that has 
Techroline in it.  Costco carries it, and it is a lot cheaper than
an unnecessary visit to the mechanic...
