hey all my car is idleing a bit rough it befor it was really bad it was betwen about 800-2000 idle i changed both coolant sensors and that sortedd that out to some extent (also replaced lambda as it was not reading correctly when we tested it) the car sits at 80 degrees and still the idle slightly surges between 900-1000 occasionly goes like the engine is struggerling to keep running ive checked for air leaks and could not find any cleaned idle control valve with carb cleaner and the map sensor cleaned the throttle body out and checked all connections are connected i kinda wondered if was still related to the temprature of my car as even if leave car to idle will never reach over 82 degrees fans do work tested that the other day it is a a/c model any help would be much appreciated thanks
