Power what? Power windows? Power mirrors? Engine horsepower? Power brakes? Electrical power? If so, to which systems?

What are the symptoms? What have you tested? What have you tried?

MAF sensor and TPS may be a place to start checking? That is an older car could be lots of things.

When I mean it loose power I mean if I left the battery terminal over night in the morning is dead. The check light comes and goes. When I drive long distance is nice but when I drive slow most of the time the car shot down. I don't know what is MAF or TPS?

THANK YOU.

Ahhh. That means there is a drain on the battery. The battery should be tested first, and if it is good, the drain will have to be diagnosed. Some things you can look for yourself include a glove box light, trunk light, or under hood light that are not turning off.

I was guessing you were losing engine power while driving.
