I had it diagnosed, but the diagnostic showed that the MAP SENSOR was bad, and I changed the Map sensor. the problem is still there. Is anyone has an idea how to fix that problem?

Could be the TPS - throttle postion sensor , a problem with IAC - idle air control -passages partly clogged not allowing enough air to by-pass the throttle plate or a EGR valve that could be carboned up an not closing all the way . A EGR valve that is sticking open can cause a false MAP sensor code. Video's on youtube showing how to check , an clean .

Hooking up a capable scan tool an viewing sensor data would point to problem .
