i have a 2008 ford escape 4 cylinder 2.4 engine whrn I stop at a red light the idaling goes up and down what causes it to do that I have tried to clean throttle body but still odoes it
could be a vacuum leak. you dont have a 2.4 its a 2.3 for future reference. Have replaced many throttle bodies but for other issues usually stalling. I guess there is no check engine light on?
