Answer
If this is anything like the Probe, look for a plastic fresh air intake tube at the back of the engine by the firewall, between the mass air flow sensor and throttle body. Check that tube for cracks that lets unmetered air into the engine. When the Engine Computer doesn't know about that extra air, it doesn't command enough fuel to go with it.
i did find that but it went in drivers chassis rail but connected to nothing.so where would the map sensor be?any ideas?
Check if there is a vacuum hose routing diagram under the hood. If it isn't missing it will show the MAP sensor if there is one. It will have a hose connected to it that goes to the throttle body or intake manifold. If you find a "baro" sensor instead, it won't have a hose on it. That is a MAP sensor that is only used to take a barometric pressure reading.
