Engine dying when coming to a stop??

Any help on this would be much appreciated. My 95 D-90 is dying when I come up to stops. It seems to happen randomly no mater if the engine is hot or cold. I'm not the best with engines so I don't know where to start. Here is my guess though. Fuel filter? Fuel pump? O2 sensor? Thanks, Chris

throttle position sensor perhaps?

could be alot of things. Does it run fine most of the time? does it start right back up every time? does it just skip past idle and die, or does it sound like its trying to hold on?

the more info you give the better chance of narrowing the culprit down.,

my vote is the idle air valve or idle choke bypass inlet is gunked up.

Steve,
It does run fine most of the time but I think your on to something cause it does just skip past idle and die. Sometimes it tries to hold on for a few seconds and then dies. It also starts right back up and runs normal. It's so quite when it dies I don't even realize that it's dead. Hope this helps. Thanks

Chris

Stepper Motor is the first step. Then Throttle position sensor (you can test this before replacing the stepper motor otherwise known as the idle air control valve).

Do you get any codes from the ECU? Is the ECU wet? How old is the cap/rotor/wires? How old are the O2 sensors.

There is no code on the ecu. I don't think the ecu has been wet. I got the truck in July and as far as I know none of the things you have mentioned have ever been touched. The truck has 60k miles on it now. Thanks

I would take out the stepper motor and clean it as a first step. The check the TPS by hooking it up to a multimeter and making sure it does not jump. Then replace the stepper motor. If you do not know when the plugs/cap/rotor/wires were replaced, they should be replaced now (they are part of the 60k service).

If none of this works, you are down to the unusual suspects. O2 sensors, a bad alternator, a bad ECU, and plausibly even some other senors could cause this.

Ron,

Thanks for the help. I'll look into all of it. My education on motors has now begun. Thanks again.

One more question for you guys. When you say clean your stepper motor, what exactly do you use to do that?

Thanks,

Chris

Where is the throttle position sensor located on the 95? Carb cleaner should work fine for cleaning the stepper motor
