Im getting fed up!! I installed Silver Faces Guages and first i the RPM Guages was off... Now.. I took it on my first drive since the guages have been installed, and the speedometer wont exceed 70 MPH and it will stick at 70 MPH when i slow down.. It will eventually drop down past 70 MPH after a few minutes... Whats going on? Rotary-Rex

 

Are you needles binding on anything? double check your installation and make sure the needles can go through the full range of motion without binding anywhere.

 

ok i checked the needle on the speedo and it moves freely by hand with very little force... what else could cause such a problem??

 

Bad speedo cable is always a looming threat. Might want to try detaching it at the tranny and manually moving the piece inside the shell (while still attached to the cluster). Could just need a good cleaning a lube.

Don't break anything.

 

If you didn't fix the tach needle problem, you can fix it by pushing it to its the stop and then push JUST a little more, it will slip on the post and go past the stop. You then just do this to the left or right until it sits on zero again...
