Oil Pressure gauge not working

ok.....my oil pressure gauge barely works....when i start it on a cold day it will shoot up to the middle then sit...as the car warms up it drops to zero....now i know the engine has oil pressure because if it didn't i wouldn't be driving it.....i was wondering is it a pain in the *** to change that out....or how can i fix it...what do i do help...thanks

sounds liek what happened to mine when my oil pressure sending unit went out....

its a simple swap....it is located right above your oil filter...kinda cylindrical thing....uncrew it....and then screw the new one in....took me about 10 mins to do....that includes jack time and time to finish a beer

Not all cars have the sender there. On my 'bird ('87), it's located at the back of the intake manifold, next to the distributor.
You can just see it in this picture...

i checked back there and there is something similar to that cylinder looking thing right next to the valve cover....how much would one of those sending units cost?
