1999 toyota 4runner, 140K miles: for 2 weeks, have problem starting when cold in morning. takes 3-4 clicks and foot on gas pedal to start. now also problem starting when warm after driving for 30mins....


Sounds like a sticky throttle if you can't keep idle. It won't hurt to try.... you can try a quick cheap trick by spraying a little carbon remover (buy at any auto store i.e. autozone, oreiley's) inside the throttle, open the valve, spray just small amount, close it back up and rev it a few times and repeat. It removes the carbon film after long use. fixed my idle issue in my cars. If its really bad you might have to clean it thoroughly but i highly doubt you have to do that.

Ok i start my 95 toyota 4runner up it will idle but as soon as it hits certain temp it stalls out on me it has a full tune up plugs wires etc also put new fuel injectors in im baffled


Usually it is the EGR valve or the EGR solenoid. Does you car have fast idle? If your car has fast idle, for example idling at 1,000 rpm instead of 800 rpm, it may be a vacuum leak. Is your car stock? If those options do not help, let me know more details about the car and i will look more into the problem.

I have a 1990 4runner with 214,000 on the motor. I have recently replaced the plugs, wires, cap, and rotar. When the truck is cold and not warmed up yet it stalls out on me. I start it and it idles high in...


probably the IAC, not usually the TPS, have you replaced the fuel filter? it could be a problem with the new wires, yes they may be new, but there is always a chance it is faulty, kind of sounds like a misfire. It could also be the spark plugs. or possibly you have them plugged the number 1 wire into the wrong spot on the distributor

1993 toyota 4runner idle too high problem


check the various throttle controlls. there should be a grey box with an unusual nut on it. have a car guy look it over. the vehicle will have a cold-start high idle for a few minutes before selling down if it's a V6.
