Hey guys, on my s13, i just did a tune up and it runs better now. However, the car is still shaky at idle and i started messing with this sensor that i believe is the coolant temp sensor however i cannot confirm. It is a ka24e
Can somebody confirm which sensor this is? I was messing with it and it change the way the car was idling which led me to believe this sensor is causing this. It bogs at times. Pics are provided below

You are correct, this is the Coolant temp sensor. The Sensor gets read by the ecu, then out your gauge cluster.

Not exactly correct. There are two sensors. The two pin with the red plug goes to the ECU, and is the one that's probably giving him problems. The other single pin spade connector is the one that goes to the dash. It's a direct connect and has no bearing on how the ECU runs.

Order a new two pin coolant sensor, and see if that clears up your bogging problems.
