What makes a Ford Mustang Run too lean?
The heat of the exhaust can also bake the wiring going to/from them over time. If an oxygen sensor goes bad, it can make your Mustang run too lean (or rich). A super lean running engine will often idle rough. The fuel injection systems job is to atomize the fuel into fine mist.
What causes a car to have a high idle?
The problem arises when the car gets some miles on it (usually 75K+) and carbon fouling takes its toll. What happens is dirt, excess air filter oil, and most notably carbon gunks up the IAC valve and doesn’t allow it to either open or close properly. This can cause an really high idle, a lumpy/surging idle or no idle at all.
