Hello again. As the title states, my LC has stalled during normal driving twice in the past couple of weeks. It will sputter to a stop and then not fully restart. I turn the key and it stumbles and idles rough for about 2-3 seconds and then stalls. After about 30-40 minutes, it restarts with no problem. I replaced the EFI relay so far, but am looking for some advice before ordering more parts. I plan to install a new fuel filter and fuel "sock" as I have had those parts for a few months. My instincts are leading me to a fuel delivery issue, possibly the fuel pump. Any ideas?
Thank you,
Try replacing the fuel pressure regulator. Mine is doing same stuff plus not wanting to restart after shutting it down for 10-15 min. I've changed a lot of fuel related parts and finally changed the fpr and bang all better. Good luck!
You haven't stated what condition the air intake tube is in; between the AFM and throttle body.
I suspect it is torn, cracked or ripped and is letting unmetered air in...
