No it's the one in the water pump that the computer reads. So you never replaced it? Even so it still seems like wiring or it would do it all the time. Do you have a scanner that can see ECT?

Yeah we have one of the expensive snap on scan tools here (modus I think?).
I swear it can read the last time I farted in the car. Had it plugged in last weekend and it was reading 157 degrees if I remember correctly. But, I wonder which sensor it was getting that info from. Hmmm. I'll swap the ect in the water pump and see what happens. I'm assuming it's not opti since it seems ok when it's cold.

Again it should be the sensor in the water pump, unless 95's are different but I don't believe that is the case. The best thing you could do would be to get the scanner on it while it's having this issue and see what it shows for ECT. Or warm up the engine and wiggle the wires to the sensor and see what the scanner shows.
I swear the biggest problem with optis is they cause people to mis-diagnose other problems because they are busy blaming the opti. |

The computer reads off the sensor in the water pump, and the sensor in the head is for the temp gauge in the cluster. I just replaced my sensor in the water pump not too long ago, you should be able to swap it out and only lose a tablespoon of coolant. Best way to get at it is underneath the car, and have the new sensor ready to go in as soon as you pull the old one out. Piece of cake.

Yup, changed the sensor in the water pump and it didn't change a damned thing.
Dammit. Kind of at a loss now. Thinking about trying another coil I have sitting here and hoping that helps...

Sensor is in the water pump its a 2 wire. The senderrr in the head is for the gauges. Its a 1 wire.

Coolant temp was 157 degrees o2's were looking good. Not sure what else to look at or what they should be reading.

Thats the first thing I do now when someones like my cars acting funny. I have a small hand held scanner that wasn't super expensive but gets the job done. to bad its a 95 and obd 1.5, he will need the correct cable. Uness he has a tech tool then nvm lol
