========================================

Sounds liek air in the cooling system. When thermostat opens the coolant
drops below the sensor and the computer thinks the engine isn't warmed
up. Mixture and timing changes and engine runs badly. Fill rad and
reservoir to the MAX mark and do it again next day too.
