loss of power?


Asked by Mar 11, 2008 at 10:28 PM about the 2004 Ford F-350 Super Duty

Question type: Maintenance & Repair

I have a 04 with the 6.0 and love it.  But I have noticed the take off takes a lot of pedal to get this beast moving.  Not too mention the mileage is terrible. I have driven other 6.0 and mine just is not comparing.  The exhaust is straight piped and have a K and N intake.  I dont beleive that a chip or programmer is the awnser.  This truck has raw power in its own. I just aint seeing it yet.  Any ideas what may be wrong.  I bought it used with 50,000 miles on it.  Could it be a back pressure sensor or what. I have no check engine light, but somethings a miss.  Thanks

I would recommend that you get your mechanic to hook up his computer to your OBD port and go for a drive. This was the mechanic can see the read outs of all the sensors. This will be a good start. I had one that had a faulty torque converter, very similar problems

may be a bad throtle position sensor.


take it in to get looked at sounds like a bad turbo and egr valve ( one takes out the other) check engine like doesn't always come on for it


mine was doing the same thing and i took it to a dealership and had it put on a computer. it ended up i wasnt gettin any boost. all that was wrong was i had a clamp come off of my air cooler. check the clamps and also the hose for any holes and that might be a big help


the only thing i can think of would be the name ford is just a peice of crap thats all
