Question about 1999 Jeep Grand Cherokee
The only way an engine can run Wide open is if the throttle plate is opened all the way, allowing a large volume of air in to the engine. Check the throttle plate and see if it is hung up or possibly the throttle cable is frayed and holding the throttle open. It is not the injectors, they operate on inputs from the PCM.
