s13 sr20det stall when warm issue!
ok so long story short, car ran perfect until i let it sit for a week, car was covered..
after sitting for a week i go to start car let it warm up take it out around the block driving normal, then it stalls out randomly and i tried starting it, cranking and getting fuel and spark and no start. i have to let the car cool down before i can start it again..boost,afr,engine temp look normal, no boost leaks, changed out cts and checked to see if maf has a change to idle when i unplug it and it does so that means maf is working. any recommendations on what it can be? or suggestions? specs red top sr20det 62 ecu all stock except for fmic hks bov isr fpr tomei srm7960 turbo tomei manifold full 3 in straight pipe and no i hardly drive car as it is not tuned yet running stock ecu, car always ran perfect when i drove it around link on the bottom to see video of issue https://youtu.be/LsULhE-vtOQ https://youtu.be/LsULhE-vtOQ Sent from my iPhone using Tapatalk |

check grounds and fuses, gfs car had issue where main fuse was blown but when cold the fuse would make contact then when hot would die like that...also check fuel pressure, ecu...sounds like something is expanding enough to keep car from going...also clean fuel filter

All the videos shows is sr20 idle lean.
Either it has a vacuum leak around the maf or a bad O2 sensor -unplug the O2 sensor -pressure test the plumbing from compressor to engine to 20psi of pressure or a maintenance issue i.e. -clogged/bad injectors -bad tps/cts/maf -bad pcv plumbing or a maf placement issue involving the turbo (can't see the turbo in the pic or plumbing so guess) i.e. maf is too close to the turbo or something |

update
replaced cts again checked for vacuum leaks looks good checked for loose grounds checked spark plugs took off turbo timer checked to see if tps is getting correct voltage and yes 5 checked o2 sensor and it’s damaged & replaced with a working one it did seem alittle better and took longer for it to stall out.. car is still stalling when at idle after 7 mins when reving it temps bounces also rpm tach after finish revin it bounces down to 0 also checked all fuses and looks good help plz... also will be checking iacv?... dont think that it can be that maybe but  Sent from my iPhone using Tapatalk |
