Rough Idle and Stalling on Ford Ranger
Problem overview
The Ford Ranger V6 is known for a rough idle, engine stalling, loss of power, and misfires, accompanied by the check engine light.
The intake manifold O-ring gaskets commonly leak, which creates a large vacuum leak. This vacuum leak causes unmetered air to enter the engine, and the fuel system becomes insufficient to compensate for the large amount of air reaching the engine.
Replacing the intake manifold gaskets corrects this concern.
