Can a bad distributor cause loss of power?
Bad spark plugs, fouled-up plug wires or a cracked distributor cap can cause spark loss, while compression loss — in which too much of the air-fuel mixture flees a cylinder before going bang — commonly arises from a leaky exhaust valve or a blown head gasket [sources: B&B; O’Reilly].
