Yogi Called with a code on his '03.

p2121. . the truck would only idle.



I cheched obdii.com. . no joy.



He stopped to check the code and it seems to have cleared itself. he's on his way to Louisville to deliver trailers and is worried about being stranded.



Anybody have a clue about the cause.



Thanks in advance.



Later,

Mark

First step... with key off disconect all the pcm conectors clean and dry both pins on the pcm and the harness side of conector. These 03s are prone to get water in these conectors causing multiple codes
