Hello there,
possibly you've had error code P0106 come up if you've used a diagnostic scanner,
this fault code can appear if there's a
problem with the MAP sensor itself or it's electrical wiring circuit, also vacuum leaks can cause issues which can bring up fault code,
as the MAP sensor is a kind of vacuum sensor, as it's measuring air volume/vacuum within the inlet manifold.
Fault code P0030 or P0032 is for pre- lambda sensor (the one before catalytic converter)
This can cause over fueling putting ECU into limp mode, as it's unable to receive air / fuel ratio readings.
I've had a similar issue to you where the error fault code for the MAP sensor kept on appearing, basically was the ECU that was faulty, I sent it of to be tested and was told the circuit for the fuel/air settings was damaged, which caused intermittent faults in other area's.
I'm not saying this is your issue but is a possibility.
Hope this helps
Si
