vacuum lhose homeless...please help!
This is my first thread. I had a front end collision with my 04 ES330. After rebuilding the front clip, I have one extra vacuum hose I need help with:
In front of the air cleaner box with the solenoid, T, etc is where it seems it should go. There is a group of three hoses coming up together near the air intake plenum. There is one extra.
I've seen pics that only show two hoses, and I've followed that. One picture shows one of the three hoses doing a 180 bend and going down again...that's my best guess for this hose.
Please help. I don't have a factory service manual, just a cheap downloaded one that is no help.

One of those hoses runs downward and to the front motor mount (actually is the left motor/powertrain mount, to be precise). There is a vacuum inlet on the mount. Probably the body shop guys had no idea and skipped it. I would bet that is what you are talking about as it’s a bit uncommon and easy to overlook.

PLZ HELP...vacuum solenoid with four hoses at LF of motor
I found a home for the vacuum line that was homeless, but found a second line also homeless. Both are by a vacuum solenoid with four ports at lowest left corner in front of motor.
Does anyone have a diagram of this solenoid?

Hmm - the "front" of the motor is on the right side of the car, not the left, and there really aren't any vacuum hoses over there. I am thinking you mean the nest of hoses by the air box at the back of the motor, on the left side of the car, above the transmission.
Take a look at this picture I posted in the past for someone else. It is in this thread:
https://www.clublexus.com/forums/es-...-03-es300.html
BTW, the photo is on photobucket and since they went pay-only at huge rates, it may not show up. If not, google "photobucket workaround" or hack and install the add-on to your browser and you can see it.
If that isn't what you mean, post a photo of what you are talking about and I or someone can help.

OK, its the LF of the car. The pic posted, and several I've found, show 2 lines coming up from the solenoid next to the motor mount. I have a 3rd line that comes up, does a 180 and goes back down. It is still homeless. I dismounted the solenoid, which has four ports, and they are all in use. Somebody else must have this vacuum line?

Did you visualize each end of the hose?
I recall something like that (doubling over/180) when I replaced my motor mount a few years ago. I can’t recall it being anything too weird, but it was a while ago. I think it might have just been a long loop in the motor mount line for no apparent reason. That motor mount is not fun to r&r so I was really focusing on other things and not that line in particular, but I know when I was done all lines/connections were accounted for and I recall the 180 loop.
Maybe someone else who has been in there more recently can answer better.

ORO is correct in his recollection. I just did the front motor mount this past weekend (2003 es300) and found that there is one vacuum line that is connected to nothing on one end. It was looped inside of a 16" rubber sleeve along with 2 other vacuum lines. If you look carefully at the unconnected end you should see that there is a small plug inserted into the end of the line. Like ORO, I've no idea why the vacuum line that's unattached on one end is there.

I found a vacuum line chart for a 2003 Lexus ES300 and towards the bottom middle bottom of the diagram is a homeless looped vacuum line with a cap. This is web site where it came from. http://www.rancholexusrecycling.com/...6211022012.jpg It’s an ad, but the picture popped up searching “2003 Lexus ES300 vacuum line diagram”.
