Speedometer seems to be whacked out, it bobs back and forth when in gear in park, or even with the truck off and the accessory on. Anybody have any ideas?

-Also, installed a flip down screen this weekend and after installation the speedo was haywire. If that helps any.

 

rabbit, quit spinnin' the tires! [sm=joke.gif]

I thought I read somewhere once that there could be a problem with loose connections at the IPC or the PCM that would cause that condition....I'll see if I can find anything.
