can any one help.... my car is running very rich. more when it is warm out, i can wiggle the wire at coolant temp sensor and it will get worse or clear up.
i pulled wire back to see if chafed but they seem to look good.

 

Sound's like it needs to be replaced (The coolant temp. sensor). I hear they are not very expensive , and they are not hard to get too either , (for a s13 anyway - unsure of the s14's). So I would give that a shot.

 

do i need to get a jdm or can i use a usa version

 

Assuming it's a S13 SR20DET , it will be/should be interchangeable with the S13 KA24DE coolant temp sensor.

 

its an sr20det... cool thanks

 

No problem.
