Read the error code, for example if it says P0303, it means the cylinder number 3 is experiencing misfires. Wiring errors can cause additional resistance, which can lead to higher temperatures even at low engine speeds. If the problem appears to be with the ignition, there could be a problem with a spark plug, ignition coil, ignition control module, or a fault in the wiring. The leading cause of premature failure of an ignition coil is due to a worn or bad spark plug ignition cable. On many COP-style engines the spark plug and ignition coil are mounted into a tube that is a part of the valve cover. A professional mechanic can swiftly diagnose the problem for you. The most common signs of bad ignition coils in Ford F-150 are engine hesitation when accelerating or loss of power, rough idle, misfires, excessive fuel consumption, check engine light illuminates, and sometimes hard starting. As spark plugs wear down, the gap in each spark plug is fired is widened meaning the coil needs to provide a higher voltage in order to bridge the gap. This excessive voltage creates a high amount of heat which consequently melts the coil's wire insulation. The coils will send irregular sparks to the spark plugs. If this happens, the coil cannot function properly if it can at all. Whenever the engine gets cold, this makes the carbon track to have low resistance which conducts correctly so that the spark will be strong enough to start the engine. Over time, the electrical windings inside the coil can become brittle and break, which disrupts the flow of electricity and causes it to fail. Another common issue with the third-generation Renault Megane is with the engine. Mostly, due to the fixed arrangement of the connectors and wires, it is not possible to swap the connectors, even by mistake.
