Ok so i took my 93 ls400 this morning, parked to eat. when i tried turning on my car again it turned on, then the idle dropped to like 100 rpm, and was fluctuating a tiny bit and i tried gassing it with no response, then it turned off. I turned it on again and it finally stayed on, idling at roughly 800 rpm. And yesterday off a cold start i started driving, then the idle started dropping and i couldnt gas it to keep it up so it turned off. What's wrong?

the whole car itself turns off...

 

go check it before you talk back :roll:

its a common problem and has been known to cause a whole rash of random problems.

 

Talk back?
I did not see the poster's symptoms spelled out in the link, perhaps you might like to fill him in just a little bit on the "whole rash of symptoms". . . just enough so that he knows he is on the correct page.
Sheesh,

the shorted wiring harness has been known to cause the following problems:
NUMEROUS electrical quirks, from the car not starting, not turning off, random dash/fuel light issues, headlights/taillights/audio issues, and more.
Transmission issues including slipping, refusing to properly go into gear, reverse lights coming on in a forward gear, harsh engagement, and even delays in shifting.

meant to say question instead of "talk back"
