KA24DE '93 so here are the symptoms...

start the car, it takes a while to crank up, than dies shorty after

unplug MAS start car, idles fine, only up to 2.5K rev, but if i hit the accelerator, it dies, i can only tap it.

unplug both MAS and TPS car idles rough, and if i hit the accelerator it dies, i can only tap it.

anytime it has the MAS connected, it won't stay running.

My friends and I checked:
TPS resistance OK
MAS connector for voltage and continuity OK
MAS is throwing voltage readings if air is passing though it

anyone know the problem? or someone around torrance wants to come and take a look? i'm clueless now.

try swapping the mafs, sounds like that is the cause of your problems. I'm also told that you can clean the hotwire if its a later one.

i have tried to swap mafs, but it didn't work neither, so a possiblity that both of them are bad... anyone have mafs laying around?

plug everything back up and try to start it. After thats done check the ECU for codes. If your car is an excepption like mine was it could be the ECU.

clean the connectors and clear the mafs and try swapping it again.
