1991 toyota 4runner 3.0 v6 starts runs 5seconds then dies will start back up for 5 seconds ata time


Hi Elmer, I'm glad to help! Elmer there are a lot of things that can cause a dieing problem. FIRST, see if it will stay running if you push the gas pedal a little bit then crank it. If it runs and stays running but dies when you release the pedal then here are a few things you can check. (1) You may have an "IDLE AIR CONTROL MOTOR" sticking and is stuck in the closed position. SOMETIMES this works, take sometime and tap on the motor and if it starts idling properly replace the motor. (2) You could possibly have a "THROTTLE POSITION SENSOR" that bad and does not signal the engine controller that the engine is at idle so it dies. If you can get it to idle then tap on the TPS when its bad it will idle the engine way up while tapping on it. If it does then replace the TPS. (3) You could also have a FAULTY or DIRTY "MASS AIR FLOW SENSOR" If the vehicle has one, some do some don't. If your vehicle is equipped with one, you can take it off and try cleaning the air flow sensor inside it. If it idles properly your good to go. If it doesn't idle properly I wouldn't rule out the sensor being bad. (4) You could possibly have a vacuum leak, vacuum leaks cause all kinds of crazy problems because it confuses the engine controller. If you can get it to idle, then you can take parts cleaner and spray around the intake manifold and if it dies right away then you have a vacuum leak that needs to be repaired. (5) You could have fuel issues, BUT, if the engine runs good while driving it down the road then you can rule this one out. These are the most common problems that occur and cause dieing problems. Hope this helps and have an awesome day Elmer.

When i stop my jeep wont stay running , cant find the throttle body sensor.


Idle Air Control Solenoid on throttle body,if that
applies

Should be at the base of throttle body & has wires
going to a connector
The other wired connector is up higher & is the TPS
Sensor,that isn't the one your asking about or the problem

You can remove & clean or replace the idle one,if you have
one.
Some vehicles idle are controlled by the computer, if drive
by wire

The car will not keep running until all warmed up.


Believe it or not I used to be a mechanic for chrysler. There are a couple of things to look at and I'm sure you'll find the problem. #1 is to check for any vaccuum leaks in the hoses and the intake manifold.I do this by spraying carb cleaner in little spurts towards a specific area and listen to see if the engine rpm raises while it is running. #2 is a carb problem--Usually with the high idle solenoid (located on the Passenger side of the carb) or the choke. Check to see if you have power at the wires leading to the using a test light or a volt meter before you start it up. If you do have power then start the vehicle or have someone start it for you while you are under the hood and examine the choke operation. B4 you start it the vehicles choke should be completely closed. If it is, it should open as the vehicle warms up when working properly. If not working properly it will either stay closed and cause the vehicle to flood out or run rough and backfire or it will be open(stay open ) and the vehicle will not stay running unless warmed up for sure.# 3 It could also be caused by a combination of the high idle solenoid holding the choke open and then causing the choke to stick open.

Engine won't idle


The Idle Air Control (I.A.C.) valve is bad. This allows the vehicle to idle with no pressure on the pedal. Replace it.
