stalling 6.0 L

[eng158]

Ok guys next question for you all. What is wrong with my truck.

here is when it stalls any ideas for the problem would be great, as well as any possible repairs.

Engine is cold, not quite at normoal operating temp, i am turining generally a hard turn, not giving gas, slow speeds and then bam it stalls. When it does not stall in those senarios i watch the volt meter get very bouncy. it will go from above 12, or whatever the middle line is, to way below to above for about 10 sec. it does it about once or twice a week. any ideas? thnaks guys.

Does it run rough at other times?

 

[eng158]

kind of but nothing like my old POS jeep. it idles rough especially when cold but only when it does the whole stumble thing.

I have had a "dying" battery make my truck run like shit and stumble, have you checked it?

 

[eng158]

i replaced it when this whole thing starterd a few months ago. helped for about a week and then the probllem started again. generally the seat heater is on, radio is on, and heat/AC is on but lowest setting. dont knwo if any of those things paly into it. thanks for the tips jeff.

.. I thoought it was another truck... sorry

 

[eng158]

Nick you had me all excited with a possible solution. thanks though. i guess the stalling truck saga continues. any one else with some input. it gets annoying when i get to the top of a curvy on ramp with a stop sign and it dies, especially when dealing with NYC traffic.

Sorry wish i could help.... I thought it was a 6.0L powerstroke:frown2:

 

[eng158]

no no diesel, wish i had one but dont have the money. at least not until i am done with college.

Sticking IAC can do it, as EGR and a bunch of other things.

Getting any codes?

My old S-10 Blazer did this. Was a stuck and clogged EGR Valve.

Check the MAF,make sure it's clean.

 

[eng158]

ok thanks i will give all of those a try. i dont believe it is throwing any codes.

Another shot might be to check the Alt. You stated that the problem went away right after a new battery was put in for a short time, it may be the alt is not producing enough at low engine speeds to compensate for all the extra stuff you may be running and with a new fully charged battery that was able to handle the extra load for a short time.

 

[eng158]

yeah i have been thinking that. yesterday the truck was really acting up when i had the defroster on. while on the highway when i would take my foot off the gas the voltage would really drop. i thought i was going to stall when i hit traffic.

Better get it checked quick before it takes anything else with it. When I worked as a mechanic I did a lot of battery, alternator stater combo replacements because people let the problem persist and it ended up frying them all.

Josh talk to Puma, he has a battery/electrical system tester. That will tell you if it is the alt. or not.

Had this problem with my dad's 6.0. It was a bad ground connection at the battery. I would say check the grounds

 

[eng158]

ok thanks all. i guess i will go use my buds tester start from step one.

Let us know how it goes
