Thank you all for the great post. I have a 2002 Lexus ES300 and was having idling problems after my battery died. I left for a trip and didn't drive my car for a few weeks. Once I replaced the battery, the car wouldn't idle properly. It would idle at 50-100 rpms and then the engine would eventually stop.
I found your post, followed the shortcut, and now it runs great again. I had notice before this the idle sometimes would be a little erratic.
The 2002 ES300 only has one larger intake mechanism, unlike the double intakes in the above pictures. I did the following:
1. Removed the stablizer bar connected at either side on the top of the shocks.
2. Removed the plastic engine cover with the V6 lettering (part is just for looks)
3. Removed the large connector hose from the air cleaner to the intake valve.
4. Removed numerous hoses that were in the way.
5. Removed the 4 bolts that fasten the first-stage carborator intake.
6. Then just squirted Carborator/Throttle cleaner everywhere there was a moving part.
My car runs and idles terrific, now.
Thank you all again. Probably saved $400. :D
