I replaced the oil pressure sensor. My oil pressure gauge goes to 0 while the car is driving. My RPM gauge is not working properly . If this site is good I will be happy to donate. I need to check the site out more.

The first thing we need to know is that the engine oil pressure is within the normal range, so to do this you will have to get the oil pressure tested with a mechanical gauge, if oil pressure is normal testing with this method, the problem will be electrical and probably with in the instrument cluster as this may also be the cause of the faulty tacho, start here.
