BUT... noticed my oil temp gauge, sometimes reads the lowest number on the gauge, even after driving for 10 minutes, then sometimes reads normal... and it does the back and forth when you turn on the car so I know its not the gauge, and I read in other threads apparently if the oil temp reads goofy (or high) it can cause this limp mode without a CEL or code... I checked the oil today, and its not low.

so it's the 370Z SENSOR ASSY OIL TEMP 22630D?

any other ideas?
