My car bogs over 10psi

Now it barely chugs down the street. Im thinking my maf is fried. I cleaned it and then took it for a spin and it was difficult to get moving. Then I unplugged it and was able to make it almost all the way down the road before it started bogging a lot again.

Does the boost guage needle bounce and flutter while idling? Steady or fluddering at 10psi?

The needle doesn't flutter at idle I wasnt able to test the boost thing cause now the car barely moves.

 
are you SURE the new O2 sensor is not the culprit, sure seems like a prime suspect.

suggest eliminating that as a cause before tearing into other stuff.

 
Yea I have the brand new one in hand just haven't had a chance to install it yet. Im going to try my maf on someone elses car today to try and see what happens.

 
So I tried my maf on someone elses car and it worked fine on there car. So then I installed that brand new o2 I have and reset the ecu. The car worked great for about half an hour and went back to doing it all over again. So im putting in brand new plugs today and im going to see if reseting the ecu everytime cause it to work.

 
So I put in new plugs today and after 2 succesful test drive still no problems. I have discovered my car was going into "limp mode" possibly due to a bad plug misfiring?

 
i thought someone said to check something like that 2 weeks ago

Ive been busy. Im still not convinced, I think its just building me up to let me down for another failure.
