no pickup at altitudes above 15,000 feet.
It does good at plains, but not in the mountains even if i push it hard, nothing in the result.
what could be the problem?

the height and lack of air for one, check your map sensor and see if any vacuum lines if any are soft and sucking together.

Cars have low power at altitude because of the lack of air, if no check engine light is on and the vacuum hoses are okay that's how it will run.
