SPARK PLUG

Icy blade revs motor quickly, but then stalls with weak gas intake; sparking fails due to gummed contacts within fuel-injection system's high-pressure pump, located near throttle body's base in engine compartment, possibly linked to a worn O-ring or clogged filter downstream of pump. Fuel efficiency also decreases due to vacuum leaks detected around intake manifold's vacuum hose connection point nearest to intake ports and possible malfunction of engine control unit that affects combustion and idling conditions within fuel-air mixture. Sparking can only occur effectively with clean and clear fuel passage from fuel tank through injector and finally at spark plug tip.
