I am having the same oil pressure problem you are, in my '89 100Q. I think what's happening is that the sudden warm weather is not agreeing with the 10W30 winter oil in my crankcase. I am going to change oil and filter this week, to see if it helps. I have noticed that if the morning is cold (<25 degrees), my pressure is better. As for the temp gauge, Angela's 90Q20V has this problem. I'm pretty sure the sensor is bad. This sensor does *not* control the overheat fans, so there's no worry there. It *does* control the engine mgmt computer, so her car runs poorly when the gauge reads 0. The engine thinks it's cold and runs too rich and conservative to "warm up". -- Andrew L.
