Default replaced MAF still bogs down at light throttle.

ok so recently i got my MAF cleaned, and then my car started bogging down in acceleration, like jerk me forward kine. i replaced my maf and now that's gone, but the bogging down on light accleration is still there. like just small kine accelerate and then it just like slows down all of a sudden. does that mean it's the maf again? or oxygen sensor or what? thanks for your help!

Peace out

the MAF is good and new so I'm pretty sure it isn't that. If it was the O2 sensors you would be having problems all over the powerband not just light acceleration. Try cleaning out the throttle plate and run some fuel injector cleaner through the system.

I'd look at the voltages across the throttle position sensor....

wouldn't be a bad idea to watch voltages on the o2 sensors as well...
