Z31 Meltdown...

[91300zx]

My brother's z31 is lacking some major power... it barely accelerates and now on top of that it has started to die out at red lights and when it idles. The idle is generally around 200 to 400, barely sputters to stay alive for like 10 seconds. He thinks its an alternator or his radiator. I think it is an maf sensor or o2 sensors... What do yall think?

well kinda a vague problem, my suggestion would be first to doa compression test, and opull the codes, get back to us and hopefully we can better evaluate the problem

Mass Airflow Sensor. The symptoms match, and the Z31s are famous for it.
