180sx Idle

Okay car starts, idles fine, then will dip and sound likes it about to stall… Any ideas. A bit of smoke coming from the exhaust.

Im thinking hte smoke is because of the temperature outside, along with the huge muffler you got lol.

:stuck_out_tongue: lol… Sounds sick ehh… Just getting seccond opinions. I heard maybe a vacum leak…?

vaccum leak causing unstable idle possible dumping to much fuel into motor. is it dense smoke or just evaperating after exiting the exhaust? motor not timed properly, different sensors, get a digital occiliscope and start backprobing wires. have fun

its as if your car was started on a cold morning. It will smoke and shortly disappear.

like the smoke will disappear but smoke will still come out( no edit)

Yea, Like DJ said it dissapears right away. There wasa diff bov on before, and now im using stock so theres some hoses that go no where. Ill get it all sorted out though. And hopefully thats the problem.

I wiggled my maf wires, and now it just pretty much perfectly at 1000 rpm

^^ Problem solved. clean your MAF
