Hello, my name is***** for the question. Can you tell me how it idles with the AC off? Why was he conpressor replaced?
Thanks. You need to fix the MAP sensor mounting and make sure that it is sealed to the manifold. If not this will happen due to the false reading of the sensor and the vacuum leak that has occurred. I would also clean the throttle body as that will help also.
