The Ford Explorer with the optional 5.0L/302ci V8 may develop misfires, rough running, and loss of power, accompanied by the check engine light illuminating. Ignition wires can rest on the exhaust manifolds if they are not properly secured. The hot manifolds will melt the insulation on the wires, damaging the wires and causing the mentioned condition. Replacement of the ignition wires, and securing them away from the exhaust manifold is necessary to remedy the rough running conditions.

Some Ford Explorer owners report experiencing a whining noise and burning smell, which may indicate potential issues with the air compressor affecting the AC system. These symptoms can stem from a failing component in the AC system, such as the compressor or condenser, leading to various AC problems. Additionally, leaking refrigerant or a weak compressor belt might be contributing to the issue. Electrical climate control problems or a faulty compressor are also common culprits for AC malfunctions in the Ford Explorer. Frequent cycling of the air-conditioning system may signal issues with pressure sensors or a failing compressor clutch. Furthermore, a faulty compressor can hinder proper refrigerant circulation, resulting in ineffective cooling. Owners are advised to have their AC system inspected by a qualified mechanic to diagnose and resolve these issues promptly.
