1990 Ford Thunderbird SC ProblemsBlown/Cracked Head Gasket Can Cause White Smoke From Exhaust
White smoke coming from the exhaust could indicate that a head gasket has blown or there is a cracked cylinder head. Our technicians tell us that removal and inspection of the cylinder heads will be required to confirm a crack is present.
If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.
While steering, if you hear a clunk or a rattle, or if you experience premature tire wear, this could indicate the inner tie rod ends are loose or worn and will require replacement.
