you may look into what is called a throttle position sensor. it basically monitors the position of the throttle and tells the fuel injection what to do. if it goes bad, the car will stall and won't run unless you give it more gas to keep the rpm's up. the throttle position sensor is typically located on the side of the throttle body, right near where the air intake hose joins the engine. they are relatively inexpensive , available at any car parts store and easy to replace. 
==========================check: 1.idle speed adjustment screw, 2.vacuum leaks, 3.ignition timing,4.carburetion problems,5.emmision vapor charcoal cannister clogged,6.dirty fuel filter,7.fuel pump not working right,8.dirty air filter,9.pcv valve bad.
================== On the back of the carb is an idle stop solinoid that shuts off the air flow through the idle passage way. I have found that the passage way can be blocked with dirt. Remove the solinoid and spray carb cleaner in the solinoid hole then blow out with compresed air. Be sure that the rubber O ring for the solinoid comes out with the solinoid and is not stuck in the hole first. Also check that there is 12volts going to the solinoid when the key is on the run position. This is somtimes fed through the alt. fuse.
================= Loose Hot Wire to control box for electronic controlled Carburator.

Are you sure you have checked all the fuses? There is a fuse box under the dash on the drivers side, and one under the hood. use a test light or meter to check them, I have seen SEVERAL fuses that looked good, but were actually bad.

Multiple cylinder misfires cause engine to die out unless gas pedal is pressed. Will not idle


the fuel smell is from unburnt fuel in the cylinders not firing , i'd have to start with reading the OBD codes to help narrow down the component/s at fault but at a guess i'd think the ign coils are at fault but the OBD will pinpoint the issue

I have a 2004 toyota rav4.yesterday the vsc trac light and check engine light came on.the vehicle idles fine but when you depress the gas pedal there is alot of hesitation.


My solution is to get rid of this car immediately!! I had that happen to me. I had my mechanic check it and it was fine about 2 weeks later the car completely died because there is a defect with the 2004 Rav4 2.4l 4cyl. engine. Toyota never recalled this defect and now I am stuck with a car that is worth NOTHING. The top of the engine is put on with a metal/screw that is too soft. It separates and then antifreeze leaks out forcing the car to overheat. There is really no way to fix this besides dropping a new engine. I am stuck without a car and at a total loss. I will NEVER buy a Toyota again. Good luck!

2002 Santa Fe 2.7 V6 (California Car) 260,000 + miles. Engine idle will increase to about 1500 RPM and drop back to normal without notice, at times difficult to start (must hold throttle about half open)...


I faulty Idle Air Control valve (IAC) can cause these specific symptoms. You could try diconnecting the IAC valve (usually near the throttle body) and regulating the idle yourself. If the fluctuations go away and you are able to hold a constant idle position with the gas pedal (if vehicle will start), the IAC is the problem.

2001 Toyota Avalon quits when at idle


Just had the same problem on the 2002 Avalon. Pulled the throttle body off and removed and cleaned the Idle mixture control valve which was caked in deposits. Runs like new now. About 2 hours of work or less. Common problem with this model I heard. Hope this helps. Some one gave me this info over a year ago and I finally got around to doing it.

02 toyota tacoma p/u 4x4 auto, no problems ever, went to run errand, will start but not idle! to keep running i have to keep pumping gas pedal but i can feel and hear its running rough. no vacuum lines...


did you lose power to the cig lighter or the auxilury one(the one with two by each other)?if you lost power to the auxilury power then its not a fuse, but a bolky black one, , this should help with that problem, as for the idiling one, change the fuel filter and if you havent change spark and wires very easy to do. Should do the trick, had the idling thing and helped when i changed the sparks and wires. good luck
