well, the car failed again sometime in the night, I did not get a chance to check log today, as i was busy elsewhere, however it must have stalled the 5 times to shut it down, the mechanic had to reset stlu fault. hey vince thanks for the input, i thought about the thermal when i was running the car, so i disconnected it and did get the prac fault, however, if i left it off for a while with prac on the screen, the car would not run again until prac was cleared. could not get a stlu with thermal disconnected. Maybe i did not leave it off long enough to go into stlu? can't recall, but i think the car stopped and leveled down to the next floor when opening the thermal circuit. the car does have a low oil switch and a hi and low temp switch . maybe the car is starting to heat the oil and then never turns off and gets oil to hot and that affects the valve? will check on it in the am, i think we are going to throw a valve in just to make the customer happy.
