Hello Scotty, recently new to you and appreciate your vast knowledge of cars. I have a 2008 dodge caliber set 2.0, 150,000 purchased 2nd hand. When I got the car it had throttle body symbol on dash. Replaced throttle body, when I was replacing there was alot of liquid sitting on the bottom. Replacing the part helped as it had no power. I also noticed a dark fluid like substance on the air cleaner. I changed that as well. I am still having idling issues and have noticed that the air filter is filthy once again. I have replace the intake manifold runner position sensor and purchased a cam shift sensor as these codes were coming up. I also reset ECM the way you showed. Puzzled by the air filter. Any advice, thanks
