Reduced engine power BY MAF senssor

[urielymc19]

I have a detail in a 2005 pontiac grand prix with the gm 3800 series III. I discovered that the MAF sensor connector is broken, and when I turned on the car it turned on but indicated: "reduced engine power", I turned off the engine and when I turned it on again it marked "reduced engine power", I turned off the motor, and now when trying to turn it on it no longer turned on, it only starts but it no longer turns on.
My question is, could that bad connection of the Maf sensor have caused the problem of "reduced engine power" twice and that the computer has entered a "protection" mode and that's why it didn't let me start the engine anymore?
Will the problem be solved just by replacing that connection?

There is no protection mode.
The MAF could have caused the message.
Try this for the no start.

The engine has already started but now the problem is that it turns off when I stop accelerating, when the needle reaches 1500 rpm and I release the accelerator it drops quickly to 200 rpm and the engine turns off, as if the realenti did not exist. I already changed the maf sensor harness that was in poor condition, that eliminated the -reduced engine power- condition.
I discovered that the supercharger cover, the one with the booster vacuum inlet and two other vacuum lines that go to the supercharger bypass valve and the baro sensor, that cover is broken and there is a large vacuum leak there,
Could this vaccum leak be the cause of the realenti not being maintained?

Twice you used the word realenti?
Yes any vacuum leak will cause problems.
