Hi, I have got an issue at the moment with a rough, irratic, and nonstable idle. All seems on point. There's no error codes, leaks none, etc. car starts but won't hold idle and motor shuts down after a few seconds of run time. Only potential culprit is fuel pressure at 2xpsi at engine shut down time. Also, I think may be injector deadtimes.


Please any suggestions reply thanks.

 

You need to have 43.5 or near that for fuel pressure. Have you played with the dead times yet? I just look up what ID recommends and it’s usually pretty spot on for what works best.

 

I have tried dead times recommended 45psi of injector dynamics flow chart, hondata ID1000 deadtime setting, and well I'm not sure if the fact that fuel pump psi upon prime/shut-off that's registering 20psi is normal. I don't see any leaks, have regulator but don't know if need to adjust.
