wont run with mass air hooked up (arm)

[Zukijames]

finally getting my swap pretty much wrapped up .. it has never ran with the mass air but i thought maybe that was because I did not have any o2 sensors


So today I bought o2 sensors plugged them in and mass air and it wont start unless I give it throttle and wont idle

unhook mass air and runs way too rich .

exhaust is coming strait out of exhaust manifolds could that be the issue ?

check that you run the right sort of maf (compare part ## of ecu and maf at toyodiy.com,whether they come for the same car)

also check that the maf is used in the right direction, and there's no major air leaks etc.

As far as I can tell I have the right one
