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.

I have a 1995 Toyota tacoma w/ the 2.4 L four cyl. It will not start just turns over. The fuel pump comes on relay clicks but it just turns over. Sprayed starter fluid in the intake and it sputtered. Any...


Check for a spark first, double check fuel pump is running and actually "hums" when you prime the motor. Check fuel filter, clogged fuel filter could be the culprit and explain why it sputterred with starter fluid but wont run without. Good luck.

I recently purchased a 2002 toyota tacoma 3.4 V6 4X4. 98K on it. when idleing and driving it misses heavily, when you let off the gas its smooth. any suggestions? Thanks


I would start with a tune up, plugs, wires, cap, rotor, air flter, fuel filter. any of these that you have on your vehicle. Also check or have checked the fuel pressure.

Engine wont idle unless you keep your foot on the gas pedal


First, try a new accelerator pump. They're less than $10 and easy to install. On the side of the carburator, near the linkage. It's simple a small rubber diaphragm.

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
