SOURCE: 1990 toyota pickup 3.0 v6,engine

This is an unfortunatly common problem with this vehicle, if my hypothesis is correct. Try this: disconnect the wiring connector going to the fuel tank, under the bed. Replace the fuse and crank the engine. If the fuse does not blow, then the power wire going to the fuel tank sending unit is shorted out to ground. I change about 15-20 fuel sending units a year for this exact same issue. Replace the fuel tank sending unit if the fuse does not blow. When you get it out, you will see the cause of the short, rust at the connection on top of the sending unit. Hope this helps.

SOURCE: Engine runs rough after about ten minutes /idles really low

Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

SOURCE: saturn sc 95 idle is not stable/ going to die

you might have carbon build up on the throttle plate, take your breather off, spray the heck out of it with some carb spray and also down in the IAC really good. The when you start it, you will have to floor it until all the black smoke is gone. Then take it out on the highway as you are in a Nascar race.
Also your egr valve might be stuck open, and even a intake vacuum hose leak. you EGR being stuck open with cause you a rough or if any take off. Take the EGR off and check it for carbon build up also, if so try to just scrape it off. If thats not possible, youll have to replace the EGR valve, those on that car vary around 130.

SOURCE: 2000 Camry Starts but dies down right away

Hello

I just worked on this problem a couple of days ago. If the motor is a 3.0 liter. The idle control valve is located at the bottom of the throttlebody assembly right below the bore for the throttle butterflies..What usually causes this valve to go bad is the mechanical part of the sensor sticks as it becomes sludged or carboned up. Manufacturer claims that the valve cannot be cleaned and should only be replaced....It's a high dollar repair to replace this sensor as your engine coolant flows through this electrical valve. The valve idles the car fast when cold, as the antifreeze gets hot the valve drops the idle down.....I have successfully cleaned several of these valves and cured the dying problems...
First remove the air filter top cover and the tubes that connect to the throttlebody. In the right throttlebody you will see a port right before the butterfly. Under the throttlebody you have a black plastic sensor with a 2 wire terminal. Remove the 2 phillps screws and pull off the electrical part of the valve. you will feel a magnetic pull while removing. Remove slowly and catch the black sealing oring, and there will be a metal washer also.. The shaft that is exposed is the mechanical control of the valve. Rotate the shaft and it should feel sticky if bad..Using a throttlebody spray cleaner spray into the small square port of the right bore, rotate shaft and spray until stickfree.....Reassemble

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.
