    The car stalls and has poor performance. Here's the codes P0171, P0174, and P1106.

    I know what the description of the codes say. The thing I don't know and what I need to know is what it takes to fix the problem.

    Re: stalling

    Replace the MAP sensor. Check all the wire connections to the MAP sensor. Check the MAP sensor mounting on the intake and make sure that the MAP sensor grommet to the intake vacuum source is seated/sealing correctly.
