When cold the pressure is 100- 110 idle when it is up to temperature 10-15 at idle, it seems to be to high when cold. do i have a problem the pressure relief valve?

I attached the spec. This is in kiopascals so when converting to PSI, on hot oil you should be between 20 - 44 PSI. So not only does it sound a little high when cold but when hot, it is too low. What weight oil do you have in the engine? When is the last time you change the oil and filter?

If there is an issue, it would have to be with the oil pump as this engine has the relief valve built into the pump. So you could be correct but let's start with this and go from there.

I just chance the oil 500 miles ago. I always have used 10/30 oil. I only had this car for a year now and I just put the oil pressure gauge last month, so I don't know if this is normal for this engine.

Okay. That is good info. I would check it with a mechanical gauge just to make sure this gauge is accurate before you go to any other trouble.
