What to blame when an ignition coil overheats?
– Motor Vehicle Maintenance & Repair Stack Exchange Ignition coil overheating: what to blame? I have got in the past ignition coil overheating, making the engine run very erratically and in some cases it even wouldn’t run at all until the coil got cooler. In one occasion I changed the coil for a new one and it overheated as well.
Can a backfiring vehicle cause ignition coil failure?
A backfiring vehicle can be an early symptom of an ignition coil failure. The cause of this is unused fuel, emitted through the exhaust system. If the issue is not addressed, serious damage can also be done to the exhaust, resulting in preventable and expensive repairs.
What causes a dry resin coil to fail?
Dry resin coils can also fail with age or hard use, but it’s far less common than with wet coils. A failing coil which usually works perfectly well be over-stressed if the vehicle is left idling for long periods on a hot day, such as during summer traffic jams.
Can a bad condenser cause an ignition coil to quit?
Yes it can! A faulty condensor can too. Absolutely they can, although they are more likely to misfire a bit first. A bad condenser can also cause similar issues. A likely reason relates to the fact that copper’s resistance increases about 0.4% per degree Celsius.
