So my car is having a weird issue, While the car is cold it runs great, but once it gets up to running temp it starts to have issues it sounds like it is running rough, and while driving it will turn off when you come to a stop.



There are no check engine lights, and I checked the spark plugs.

 

Test the ECT sensor. If it's bad, the ECU thinks the car is cold when it's not and causes it to run poorly.

 

If the ETC sensor was going bad would my temp Gage still work like normal?

 

Yes, two different sensors. 1 wire sensor is the gauge, 2 wire sensor is the ECT that goes to the ECU.

 

Replacing the ECT Sensor and O2 Sensor fixed the problem. Thank you.

 

Good to hear you got the problem sorted.

Thank you for returning and stating the fix for future users. Cheers!
