2003 Ford Explorer XLT Wants To Stall At Low Idle,, especially when at a stop light

How does it idle in park , does it run ruff or smooth? Are any lights lit on the dash , check engine etc. ? Could have a partially plugged IAC air passage .idle air control (IAC) valve ! The engine computer uses the IAC to control idle , when under a load such as when put into gear the computer raises the idle ! It does this by allowing more air to by pass the closed throttle into the engine raising the idle ! If these air passages clog they restrict the air flow an cause a idle problem ! Now if it runs ruff at idle in park you could have vacuum leak ! Rough Idle How to Fix Ford Taurus Engine Stalls at Stop Signs

The battery light turns on and then when then when i put my stick shift on neutral i turns off

You have to get the idle adjusted right on the carburetor and at the throttle controls on the carburetor. Nissan varied the idle controls a lot from year to year. Your '85 might be pretty simple and straight forward. I might be able to help you through it. You would want the engine running with the carburetor exposed-so with the engine off, take off the air breather assembly. Yes, they are complicated little pieces to get off, but has to be entirely removed. There will be one vacuum connection to pull off from the bottom of the assembly. This is manifold vacuum, so you don't want to leave it open, will make the engine run funny-rough- close it with a golf tee, or a screw or bolt that fits in the hose end tight. Check for other vacuum lines, may be other small lines that are actually fresh air vents. If there is an electrical connector to the breather assembly, just unplug it at the engine. That would be an air temperature sensor , if so equipped. Now you can see your carburetor controls, look for an idle speed screw that you can turn in to raise the idle, raising the throttle plate raises the idle.

This rough idle business; With the AC on at a stop, the idle is about 600 to 700 rpm and vibrates the cabin. Can the dealer change a computer setting to correct this?

Problem on focus too . Without A/C on it idle's smooth . With A/C on the PCM - engine computer should raise the idle rpm. 850 . The only way to raise the idle would be to have PCM flashed programmed with up dated software . Adjusting the idle anyother way would cause check engine light problem , Wouldn't be able to get it to go out. Your best bet ,take it to the ford dealer and have the PCM reflashed .

My vw passat (an automatic) stalls when I have to come to a stop a lights, or even sometimes when I have to slow right down to an 'almost' stop - any ideas what the problem might be ????

Probably the IAC which control the idle but usually you will see some erratic idling as well. Pretty sure something to do with the control of idle and fuel. Maybe you need to clean throttle body and raise idle some might help. Have IAC checked.

Idle raises at a stop.

When you have the car in gear there is a load on the engine. If you are for some reason not getting good fuel then its trying to compensate by kicking the idle up. When you are just in park there is no load so its not struggling. Regularly using a fuel system cleaner will help with rough idle, as well as hesitation. Also it might be good to check the fuel pressure regulator.

Engine idles higher at stop light

It has a problem with the idle quality..when you use the heater with the a/c compressor it will raise the idle and get the fuel it needs to run...look for vacuum leaks.....hissing sucking sounds
