Problem is after my car is done warming up.. I drive around a little bit.. then once i hit a stop light my car dies.. It doesn't die when im driving but only when i put the car in neutral. I've check spark plugs, fuel pressure regualtor shows 40 - 50 psi. When i drove my car N/A that car never died.. but once i threw my turbo set up on it just started to do that.. I brought my car to the tuner and he said sometimes if you car idles around 1000 it not enough to keep my turbo spool.. so he raised my idles to 1350 and it still died.. he raised it again to 1500 and it stayed on for a while and then died.. So im guess that wasn't the problem.. I don't think my ignition is bad.. But i do think it has something to do with the fuel.. I am running AEM EMS and i was thinking maybe the tuner tuned to have too much gas at idles so that why it dies.. I have denso 720 cc injectors. He also check the throttle body for me so not to much air was comming in. But this problem only happen when my car is warm/ hot or been driving for a little bit.. but when it is cold it runs fine.. Can someone help?

 

You tried messing w/ the idle screw already?

 

my guess would be to inspect the idle.

meaning check the idle screw and also take a look at the iacv and fitv.

the fitv is what control airflow when the car is cold, once it warms up it is not used anymore.

you could have some sort of blockage.

remove the throttle body and take a look. i believe the top hole is for the iacv, and the bottom is the fitv.

i would look at these first.

 

i have check that idle screw and also just bought a new throttle body.
