I also have a 2000 ES300 and I had the same problem where it would idle so low to the point of stalling and sometimes it would and one time I was stranded while it did the very thing you described, it would start and then immediately shut off. This went on for 30 minutes before I finally got out of there. The idle air control valve attached to the front bottom of the throttle body against the firewall is the problem. However you do not need to replace it you can just clean it. After so many miles it becomes dirty and clogged. Only seems to be an issue on 2000 and 2001 vehicles with the Twin Throttle body. To fix remove the rubber throttle body hose closest to the firewall( if standing facing the driver side fender its the throttle body on the right hand side) once you remove the hose you'll see a hole in the bottom of the front part of the throttle body. Obtain a can of throttle body/air intake cleaner and using the straw that comes with the can insert into the hole(you can use force, you'll feel the straw flex around a bend in the hole) and generously spray into hole repeatedly. I recommend using an air duster and straw inserting in hole to blow out excess dirty fluid in between and than spraying cleaner again into hole moving straw in and out going deep as you can go with the straw. (normally about an inch or so) Be generous with the amount used. After your finished leave the last dose of fluid in the hole to flush through when you start the car.Reconnect hose, tighten screw clamp, start car, and go drive for a mile or so.I had to use about 1/4 of the can to clean. If you notice the problem returning repeat the procedure. I had to do this about twice before the problem stopped reoccurring. This will NOT damage anything in your car. If the car wont start due to hydro-lock, DON'T panic. Just keep trying to start car pumping gas it WILL start and wont damage car. You might notice fumes and/or smoke coming from the tail pipe as well. This is also normal and will only last a few minutes or so depending on how dirty it was to begin with. If you like you can also use some Sea Foam Deep Creep. The product will be double to triple the price of the throttle body cleaner though.

You need to have a mechanic replace a sensor that went bad and has caused that to happen (idling control sensor) this happened to my 1999 ES and that solved the problem. I had this done at a Toyota dealer for about $300. Also check the battery terminals to ensure they are fastened tightly because this can also contribute to your issue

2001Mercedes E320. Drives fine until I take my foot off gas peddle the car is still running but gas peddle does not work turn off then on runs fine until I take my foot off the peddle what is happing


If you have drive by wire. I would check the TPS first. It's under the gas pedal. (bad location). Unplug it and plug it back it. (bad connection) see if it still does it. If so. Have the codes read. I replace a lot of these because of the location. Bad water and moisture source.

Car will not stay turned ON when cold


Try this. When you first try to turn your engine on, keep your foot on the gas pedal. The car should turn over but not start. (don't worry, its not supposed to). Take your foot off the gas and turn the ignition on again, but Don't touch the throttle this time. That should set your choke correctly. To summarise: Turn key with foot on Gas. Take foot off Gas, and turn key again.

Drive vehicle down the road for 20 minutes and come to a stoplight engine stops when you take foot off gas peddle and go to apply brake. To keep vehicle from dying you have to hold the gas peddle down


Have you changed the timing belt? or timing belt guides? How many miles? This does not necessarily have to do with fuel.... Could have to do with air intake or timing as well....

2001 dodge dakota will not start


Sounds like a bad battery, or bad/loose connection there. After the battery is replaced, or disconnected, it will need a little bit to relearn how to idle.

Truck starts and idles down as normal. If one guns it the revs will soar. If one tries to increase the rpm gradually the engine quits at about 2000 rpm. At this point if one lifts ones foot of the gas...


You may have a vacuum leak. My problem was with the L-shaped rubber hose at the top of the engine near the firewall. It had collapsed and dry-rotted. Replaced it and my truck runs like a gem. I believe it was fouling out my coils on plugs. This may not work, but would not hurt to try. Good Luck!
