Advice needed please (low idle & hesitating throttle) - Toyota Yaris Forums

Just my .02 you said it ran good with the maf unplugged.
Maybe look at the intake hose after the maf carefully make sure there is no weird cracks or breaks in it. Take it off and shine light through the whole thing and if you can see through I feel like that would be ur problem.
To me it seems like the maf is getting a wrong reading.
I doubt it would be the cat mine has been bad/stinks for about 3 years and I do not have the same problems.
(Also if you want to be really cheap cut the cat off and replace with test pipe/gut the cat. for testing purposes of course.)
