Well lets see ive got a 92 lx 5.0 that has 140,000 miles on it, its an automatic and has within the last month recieved new plugs, wires, fuelfilter, cap, rotor, cold air intake, 3 row radiator, 160 degree thermostat,and a fresh oil change. Yet my start up problem presists. When the car sits for more than a day it requires up to 5 cranks before any life is breethed into it, even then its a rocky idle. Yet once warmed up it starts 1st crank every time. WTF! is going on? vacume problem? ignition? any help would be appreciated

sounds to me like your fuel pressure is not staying primed like it should, and you also need to get rid of that 160 tstat, get a 180 so the car can run correctly.

1st off, the 160 stat is too cold for the car. Not causing your problem though.

Try this, next time the car has been sitting, cycle the key on and off 2*3 times then crank her over and see what that does. You could have a week fuel pump and it's not holding enough pressure to keep it running when first started. If that works, you need a new pump. If not, you'll have to look at other causes.
