THE MAZA MPV JERKS
The PCV is a valve and a hose, that sucks engine ring bypass gasses and reburns them. if it plugs up the engine leaks oil.
if the hose cracks it sucks air and the AFR goes lean and bucks.
jerks.
only on engines (unstated) that use a MAF sensor.
engine that use a MAP sensor ,race too fast with full power and no jerk with air leaks.
next time post engine type. as we can not guess this.

2.0 L FS-DE I4 (99-02)
2.3 L L3-VE I4 (02-05)
2.5 L GY-DE V6 (99-01)
2.5 L AJ V6 (99-02)
3.0 L AJ V6 (02-06)

Check to see if you have a MPV that has been included in the recall for the PCV line. Yes it is difficault to get to on your own, however they have special tools to reach behind the manifold to remove the line and install a new one. If you do it on your own it is very difficaul and will take a few hours as a I did before I found out about the recall. The service dept. should have asked you about the recall when you went to get the part from them. Where I got pissed was when they did replace the hose the faulty line had fouled the pcv valve and they did not bother to replace it and that is tucked under the intake manifold and under the fuel rails.

The drain hose empties on the passenger side, front, behind the front wheel and in a bit towards the center of the car. You need to run a long wire up it to clear it.

it could be an air leak from a vacume pipe or the inlet mannifold gasket

No, it's the fan module itself. They were recalled but not ALL of them. Mine did the same thing and yet it wasn't part of the recall, go figure. The problem is that if it runs all the time it will run down your battery. The other issue is that sometimes it won't run at all and can cause your engine to overheat. I had mine replaced, cost me a couple hundred bucks. Hopefully yours is under the recall. Check with your mazda dealer and don't let them feed you a line of ****. It's a known issue.

PVC Valves do not need to be replaced
Never have
99% of them, have been on the valve cover
for at least 40 years
Unless you have a pcv vacuum hose leak
they do nothing, as far a your engine goes
They are there to regulate crankcase fume
evacuation
Need to start studying & stop listening
to all the hype,including repair shops that
sell these things for no reason.
