Ok, here's the test at running temp:

Engine temp gauge at 80C

-4 pin sensor reading = 270 ohms diag 1 and 290 ohms diag 2.
-1 pin sensor reading = 64 ohms
-2 pin sensor reading = 520 ohms

-The 4 pin sensor is just a little bit out the spec. of 325 ohms at 80C and 247 ohms at 90C
-The 1 pin sensor is just in the spec. for 80C (-3ohms) at 64 ohms.
- The 2 pin sensor, I cannot find any spec in my shop manuel, what it should be??

Did the small difference between the spec for the 4 pin sensor and my reading can cause the SSS(sudden Stalling Sydrome)?

Thanks again
Max
