Hi all,

My brother's 06 has just started having tach problems.the tach will jump all over the spectrum.running down the road it will go as high as 3600 and as low as 100.truck runs perfectly and has not had any problems.

Any ideas?????????

There have been several instances of tach issues with the '06's. In fact mine does it. You can have the dealer replace it or you can have it repaired. Here's one place that does it.
