I was resetting my gauges. Everything was looking good till I turn the car on. The tact is working fine. The speedometer is sticks to zero till i hit a bump then it goes the the right speed , then sticks.what could be wrong. I was looking at kspec at the maxtrim gauges, is that a whole gauge cluster or just the face?

 

What do you mean you were "reseting" your gauges,...
If you took the needles off and put them back on,... the speedo needle is on too tight / close to the gauges

 

when i turn my car on the tach would jump to 3k rpms and the speed would jump to 10mph. So i took the needles off and put them back on...

 

Have you touched the needles before this?
Did you change your gauges or pull the needles off before?
