Misfires, coils, and spark strategy: notes for when a tow feels like overkill

# Misfires, coils, and spark strategy: notes for when a tow feels like overkill Humidity, sun load, and idling in traffic change how A/C and cooling behave—context is diagnostic fuel. If **safety is questionable** (major brake loss, heavy overheating, flashing MIL under load), we advise **stop driving** and a clear plan. Message with **year, make, model, mileage**, and **when the symptom happens**—it saves time on arrival. _Educational overview only—not a remote diagnosis of your vehicle. Estimates depend on inspection and your approval._
