Just bought my truck and the tach doesn't even move off of zero unless I punch it, then it goes straight to 4k, then wraps all the way around to the other side of the peg. I have a 4 year warranty but it only covers power and drive train (besides injectors for some reason) so it probably isn't covered. Has anyone else had this problem? and if so, was it an easy fix?
yes, click on the link. there is a write up in the thread(i think page 3) of how to fix the problem with the 06 tach. very simple to do, good luck.
