1992 240sx starting problem

[maker_moan]

I just recently bought my first 240sx and eventually started having starting problems. When ever I start my car it tends to rough idle then die on me, or just rough idle real bad where it is about to die but saves its self aha... I changed my spark plug, starter, fuel pump, fuel filter. I'm just wondering what the problem is, I'm thinking of checking my iacv when I have free time but I want more opinion from fellow 240 owners before I go looking around again.

thank you for hearing me out, looking forward to hear your guys opinion.

check your maf...

change all coolant related senors, clean your maf and check the voltage, change your 02 sensor just cause i'm sure it's old. check for vac leaks and IACV

clean your idle air control valve with brake clean and WD-40. if its your valve then replace you PCV valve that's probably your problem
