My truck will not idle and there is water coming out both exhaust pipes, what would cause this?
A small amount of water coming from the tail pipes is an indication the catalytic converters are working correctly. A heavy amount of water and or accompanied with white smoke is an indication of a blown head gasket.
Of course checking for any computer codes would be a good place to start diagnosing any engine issue.
A poor engine idle can be caused by being in need of an engine tune up. A faulty IAC – Idle Air Control Sensor or other sensor, vacuum leaks or internal damage.
