Replaced the coolant sensor in the top of the block. It's the "updated" sensor so I had to cut and spice a new pig tail to make it work. I first tried just modifying the sensor itself to fit the old pigtail (removed a small shelf of plastic) but it was giving me these same problems so installed the recommended pigtail but it's the same.....
When started cold and allowed to idle until warm the gauge goes up into the normal position as usual (dead center) but as I'm driving the further I go the lower the gauge reads. During continuous driving it settles at the top of the white block and seems to stay there. If I stop at a light after about 30 seconds it begins to go back up. If I sit there long enough it will return to normal centered reading. Then it will start going down again as I drive. It never goes over the middle. Also when the gauge is reading normal the car idles as normal but when the gauge is below normal while driving and I'm stopping for a light, etc. I get hanging revs(like it was still warming up) until I come to a complete stop, then it returns to normal idle.
What gives? Anybody have any ideas? Better yet know what the problem is? Could it be something to do with the "revised" sensor. Does the computer need to "learn" the new type of sensor? I get good heat and all hoses warm up as they should, when they should and even used an infrared to verify so I'm pretty certain it's not a tstat.
