Will a faulty manifold absolute pressure(MAP) SENSOR cause my fuel pressure to drop? And make the car jerk at take off and feel as if car is losing power during gear changing?

Only the FPR controls fuel pressure which is manifold pressure related. However the ECU uses MAP to calculate how much fuel to inject.

I just put a new map sensor and cleaned the injectors the car is still throwing map sensor code and is still jerking after it heats up also has weak start then idle jumps to normal rpms after about 3 seconds
