The temp dropped 20 degrees yesterday during my shift..Went to start the truck( which normally fires right away unless I short stroke the key.) Anyhoo, at 34 degees F, the truck shimmies and chugs like it was 10 below zero..As I released the key ,I noticed my GPR-LED lite was not lit.I did get home and after a refresher course on Guzzle's site for testing GPR and a trip to Auto Zone, It was hardly an inconvieniance...Saved a lot of diagnosis time...Now off to the hunt!!!

 

Cool cool This is something I need to do. Soon
