s13 maf issues, ive tried it all

[240killer]

i have a s14 motor in my s13 and it wont idle if you plug in the maf. car has no egr, s13 intake, and all the stuff you need to do to put the new motor in. thing is i reused the s14 iac and the other valve that right by the iac.
would those s14 sensors cause this flooding out problem when the maf is plugged in?

have tried multiple mafs and ecus, even out of a car that just drove to my house.

checked the wiring with an olhm meter and everything is reading correctly, even the maf. so the maf is reading/sending the signal properly the ecu just dont like it...

any ideas and would the different iac cause this issue? thanks all

Check for Vac/Boost leaks

[240killer]

ok. i checked for vac. leaks and fix them. help out. i could keep the car running with give it gas but still stalled out when not giving it gas. there is still a little leak but i was just wondering if there could be anything else that i should be looking for?

thanks
