High oil pressure causing loss of power
My problem is the opposite of anything I have seen. I have a sudden loss of power and cannot accelerate after a sudden spike in oil pressure in my 2003 f150. Any suggestions?

Sounds like you are getting excessive backpressure. Check your cats for being clogged.

The Factory gauge is a "Have any pressure? If yes then send power to gauge. If No then dont send power to gauge and turn on the Oil light" kind of gauge. It does not actually show you what your pressure is. Its a mechanical Dummy gauge.

From what seemed to be the consensus here years ago was that the pressure gauge was more than just an on\off switch. The problem with the gauge was that it's not a calibrated gauge. This means where the needle on the gauge lands means nothing. Three different trucks with wildly different readings by the gauge could have the same pressure reading by a calibrated gauge. I'm guessing that's why Projectsho is saying it's impossible for the gauge to give any indication of pressure. It's really not meant to otherwise it would be calibrated. Also any change from where the needle typically ends up is no indication of how much the pressure has changed. It may be a lot or it may mean almost nothing. The use of an actual calibrated gauge is needed to measure actual pressure.

It's not even a gauge. It's simply a mechanical idiot light, pretty much like I (and Dragxx) described. If the oil pressure is greater than 4-6 psi at the pressure switch mounted on the oil filter adapter housing, it's supposed to read mid-range or thereabouts.

The only way to know the actual oil pressure is to install a actual oil pressure gauge. Its been years since i sold my 2003 but IIRC on a cold engine my oil pressure was mid 60s, once warmed up it was mid/high 20s.
The factory "gauge" is nothing other than a on/off indicator.
