Need help with stalling !!! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So I'm having an issue where my car almost stalls coming to a stop. It drops down to about 500 rpms sometimes lower and The oil light flashes. Occasionally while driving my cel will blink 2 times at most. The temps have been to 100 Celsius during normal driving.

Set up is red top Sr With 550 cc inj. 50 trim .48ar. Power fc.
However my tune is for 550 ' s and a 50 trim .63 ar. I blew the turbo so the .48ar is just a temp solution until mine is finished being rebuilt. Idiotic I know.

Could that be my problem^^^ or could be something els like a bad tps and the oil light flashing is just cause the pressure is low when the cars about to stall?

Did you check the oil? There's a reason it is flashing .
Maf or iacv?

Yea oil level is fine no leaks not burning any. I'm running a map sensor

I did not check the iacv.

Boost leak test it. You could simply have a vacuum line that's either not on or completely unplugged

I'm going to boost leak test it today. I also forgot to mention there's a weird vibrating/clanking noise when I hold the gas steady at about 3k. Not during acceleration or deceleration

Update vacuum pressure is fine no leaks.
Clanking noise only happens when throttle is held at content speed. Not during boost or idling.

Almos t sounds like it's coming from the timing chain area...

Sounds like the side effects of an atmospheric BOV on a MAF car. It almost seems like it happens more often with the Greddy type BOV's too.
It annoyed me so I just used a radiator hose to recirculate the BOV back into the intake and it runs fantastic now.
