I first noticed it idling to fast when started. I would shut it down and then restart it and then it would run fine, this went on for awhile and now it just dies whie driving, it starts back fine and you can drive it on down the road a little further and it will die again. It does not do this every time you drive it. It does it once and then might not do it again for a week or longer. Can anyone help me?
Hey,,sounds like your fuel pump is about ready to stop for good... I went through this same thing with my suburban..(everything is in the gas tank) ....you have a "trap door" behind/under the backseat that make access much easier
SOURCE: motor shuts down
Have you checked/tested the fuel pressure? sounds like a bad pump and or plugged fuel filter, check the pressure, if it is low replace the filter, if that still doesn't help you will need a new fuel pump, it is located in the fuel tank.
SOURCE: the truck dies while I am driving
I read this in a blog and it worked for my truck. I cleaned the throttle body and the air filter. It seems to be starving for air when you are just at idle cause it would not die when I was going down the road. Only if I was pulling into park with the rpms really low. Just pull the intake off and clean the throttle body. You will see a bunch of gunk. Clean it until it turns silver again.
SOURCE: 95 lumina dies and then starts back up and runs fine.
Electrical problem can be the most frustrating and difficult to diagnois especially when you are not phsyically at the vehicle. I will attempt to point you in the direction you should be looking. Right off the bat it sounds as if you are running low on power when the demand is high. First thing to suspect is the battery. For some reason it is low on electrical power.
Next thing is to figure out why. The first thing I would check are the cable ends. Are they corroded? It may not look as if the are, but they still could be. Clean them thouroghly.At times, when they are corroded that may be enough to stop the flow of current from the alternator to keep the battery charged up. If they look good, you may want to put your battery on a charger. Pay attention to the meter and see how much the battery is down. If it taking a lot of charge it could be it needs replacing, but charge it up and see how it works. Remember when charging a battery, first remove the caps and see if the cells are low on water. If they are your battery is probably the culprit. When a battery starts using water it's usually because some of the plates have over heated and warped, which causes them to touch each other and short out. BTW, when charging a battery make sure you remove the caps during charging. So leave them off after you check the water, AND if you need water use only distilled water. You can buy it just about anywhere, grocery store, Walmart, KMart, etc.
Check your altanator belt and make sure it is tight and not streached out. That could also be why the battery is not keeping up with the demand.
If that dosen't cure it, next take your battery in and have it tested and see if it is up to snuff. I hope this helps you and please let me know through your rating of this advice.
Engine stall or RPM fluctuates
at idle.
This problem
is commonly caused by a dirty automatic idle speed control valve and
throttle valve. Buy a can of throttle valve cleaner (do not use
carburetor spray cleaner!) from NAPA or Carquest (made by CRC
chemicals) and spray it into the air intake while the engine is
running, use up about 1/2 the can, engine will try to stall hold the
speed up, shut it down and let it soak for 30 minutes, restart and
blow out the remaining fluid, shut it down and disconnect the
negative battery cable for 5 Min's to reset the base idle control.
Below is a picture of the switch I mentioned.
