Everyone says change your ECTS. what exactly does changing that do, since you all seem so smart.

the ECTS for all s-series before 2001 (i believe that is the year) is made of resin. After a period of time the coolant will actually eat through the resin creating visible and sometimes not visible cracks. the coolant leaks through to the electrical connector sending false readings to the PCM. that is also why we recommend check the connector and replacing it as necessary as well. the new ECTS is Brass and so cannot be eatin through by the coolant

i'm dumb as a pile of bricks but i'll give you my observations after changing it.

my idle behaved
my temp needle stopped going all over the place
smoothed my idle (and i have video to prove all three were nuts)
i think it improved my gas mileage a little (still testing that out)

actually i think my problem was more geared to the connector going to the ects itself because the one i replaced was an aftermarket brass.

First off, if yours hasn't gone bad, it won't do anything but, keep it from going bad. If your car's never had it done and you own a 2000 or earlier, replace it before you have problems. It will make you think your car is ready for the junkyard. If you have a 2001, you need to check it. Some of those have the old style plastic tipped sensor as well.

This sensor is critical. There are two main sensors that control the fuel/air mix. They are the ECTS and the front O2 sensor. The PCM can get some idea that the front O2 sensor is going by how often it switches and will set the SES light. That's not the case for the ECTS. It rarely sets a light and when it does, the light usually indicates something else. For instance, I had an ECTS go and got an SES light for the transmission temperature sensor being out of range.

As I have found out and said before! It is "AMAZING" how that little $20. part can cause so much trouble!! As so many others smarter than I have said, Change your ECTS and check your oil!!!!
