Why would my temp gauge go crazy all over the place when i hit some bumps? Just started to do this. Is something loose somewhere? Thanks in advance.

if its the earlier model check the wire and the sending unit on driver side head it should be towards the back of the head above the exhaust manifold

make sure your radiator is full
x2 check the wiring
make sure your temp sensor wiring is'nt touching plug wires
test yout temp sensor
