I had traveled about 11 miles and pulled up toa light. When I accelerated the car went and then felt like it bogged down. I had the codes read and it said that I needed to replace the MAP sensor. Did that and have seen no improvement.

Would you have any clue what I am dealing with?

Check and see if the snorkel is off at the throttle body, or if that plastic resonator has come loose at the air inlet tube. It sounds like an air leak after the mass air flow sensor, the map sensor code will set falsely due to expected vs. Actual engine vacuum based on airflow readings and throttle angle. The resonator is the piece that you have to lift up off of the pin to change the air filter.
