stalling problem

hey. im new to this forums and im not too sure if this is in the right section. i have a 91 240sx ka24de and it starts normal but then after 30 seconds it stalls. im pretty sure my maf is good and the pigtail for it. i even pt a new ground for it. i was thinking o2 sensor. any ideas? thx in advance.

Hey Blaze. I’ll let the 240 guys answer that but you should post up an intro so we can welcome you formally.

need help.

clean out your throttle body. And your idle air control valve.

It would not hurt to change your o2 sensor and a coolant temp sensor. they are very often bad with our old cars
