What does the oil pressure gauge read now is it still reading high or reading low with the engine running?

Is the engine making any noises at all when running?

Let me know so we can continue,thanks Pete

no noise when it idle it reads low, when you press on the gas it peaks out to the right max reading.

O.k.,with what is described here that is occuring and since you have no engine noises with this fault here this sounds like you have an internal electrical fault with the engine oil pressure sender itself.This is the most common cause for this issue here.I have had to replace this sensor several times before for this issue.The other fault can be the instrument cluster itself at fault internally needing repaired but most common is the oil pressure sensor/sender needing replaced.

The way the cluster is checked is with a scan tool plugged into your vehicle that can communicate with the instrument cluster data list to see what it shows for engine oil pressure.If the instrument clusters data list shows the same as the way the gauge is acting up then the oil pressure sensor needs replaced.If it shows a correct reading with nice smooth oil pressure readings at idle and revved up then the fault is in the instrument cluster needing replaced.

I suspect this is only the oil pressure sensor itself needing replaced to correct this fault here.
