i notice my car runs hella rich, basically spitting gas out of the tail pipe, and idels really funny, u guys think it's the ECT sensor is going bad? i check but there's no crack and i also checked the connection. if i were to change my ECT sensor (coolant temp sensor) what year and model should i get it from, b18a1(90-93 integra) or b16a2 (94 vtec del sol) ? thanks for the help guys.

 

they are all interchangeable
