hi everybody,i love this forum,learning a lot already,i have a problem i can't find any info on,
just bought a 93 ls400,about 140,000 miles,if the car sits for 10 hours or so it's hard to start,acts like its running on 4 cyls for about 15 to 30 seconds then perks up and runs great,let i sit 4 to 6 hours,starts right up, any ideas of what to check?? thanks

 

Sounds like you might be losing fuel line pressure.
I would check for minor leaks in your fuel line.
