engine cough

[shuy1]

I have a 2003 6.0L. When i accelerate there seems to be air blowing back through the air filter. When this happens there is a lack of power. It also does this occasionally when i let off the throttle suddenly. The best description I can give is that it sounds like the engine i coughing. does anyone know what this is.

Make sure you bump this post up in the morning when everyone is awake. The best way to get hits on a thread is reply to the post so it comes to the top of "Most recent posts" so people can see it. right now all the techs are at the bar. they will be back tomorrow late morning or afternoon

I have no idea how to fix engine problems but until you get it figured out I would park it so you dont damage anything more than you have to
