I've often noticed the oil pressure around 90 when the vehicle is cold and during idle. As it warms up it begins to come down. It drops during acceleration and rises during idle. Once warm, it stays in the 40's range. It's been that way for the 3.5 years I've had the Journey. The dealer always does the oil change and uses the specified oil.
Hope the repair is done and everything works out.
I do believe you have that backwards, the oil pressure should rise with RPM (accelerating) because the pump is turning faster, and should be lowest at idle when the the oil pump is turning slower.
