instrument voltage regulator
 

My temp stays down under the 130 mark no matter how long the car runs for.. and the gas is up way past full and never moves down.. and sometimes i watch my oil gauge drop down under 0 then bounce right back up .. is this what it could be.. and also where is it located?

could have a bad ground in the cluster or bad IVR

im pretty sure its the volatage regulator.. ive read alot of people with the same issue.. the problem is ford stopped making them in 2003 i need to find somewhere that i can get one

where can i find the IVR .. i cant find them anywhere..

The gas gauge reading full all the time sound slike an open ground there. Is it possible that both sending units for oil and water are bad? Those should be available...

everyone told me its this Instrument Voltage Regulator.. it controls all thoses gauges and has a history of going bad.. the problem is no one makes them anymore

try this out... dont know if yours looks like this but just maybe...
