2005 6.0L running poorly... could use some guidance.

[i_timmers]

Hello All! I have been experiencing some issues with my completely stock 2005 6.0L automatic 2wd work truck and hope someone could help out. On Monday, while my truck was in park and idling, I heard a slight change in how she sounded(the tone changed) and it hasn't been the same since. I checked the gauges(temps and all levels were all ok), no CEL, all seemed fine so I shut it down. I pulled the fuel filters(both of them) and they were a lil dirty, but not as bad as I expected. New filters and o-rings installed... she fired right up. After letting it idle for 15-20 minutes(to purge the air out of the fuel system), I took it for a drive. It is missing and surges pretty bad when your cruising(from 40mph all the way to 75+mph). Under full throttle, it smooths out slightly but has nowhere near the power it used to have. When your coming to a complete stop, it also surges some(chugs) feels like warped rotors without the pulsing pedal. Also, no unusual smoke at all from the exhaust.

The truck starts right up, hot or cold.... I always let her warm up properly too. Being that there is no CEL, does that mean there is no real way to see whats really going on with it? I have driven it all this week, added fresh fuel, Stanadyn additive too and it runs just the same... crappy. It has 88K on it and am really trying to determine whether or not the repair is under the 100K warranty. The company I work for owes me a bit of money and I really don't want to commit this truck to the dealership without knowing the repair bill is affordable.

If someone is able to scan it or at least give me some ideas as what to check for, I would be extremely grateful. The truck is driveable so I can go to you also. I do live on the North/West part of town.


Thanks in advance,

Tim

Clean the EGR.

Clean the EGR.

Is this a tough procedure? I know we have had several trucks that have had the EGR valve replaced under warranty..

Cleaning the egr valve may help, but, sounds like you have a injector issue... either way.. 100 ded at the dealer should cover it...

Thats my thought... just gotta be sure. You know how Ford is with that 100K warranty, anything to weezle out of covering it. The best is how they charge 100 ded per repair.... even if they are part of the same concern. I've seen them do it and it's crappy.

there is a good chance an 05 is out of the 5yr range ,, it all depends on when it was first sold ,, call the dealer or ford with your vin to verify

If it is out of warranty let me know and I will scan if for you....

[ZMANN]

what scanner do u use?

[Mad Max]

AutoEnginuity PC Scan Tool...

[i_timmers]

Well, the build date is 05/05... so it has at least 3 months left of warranty.

Mad Max Barry... if you can scan it, that would be great. Please let me know when your available and I'll come to you. I don't expect you to go out of your way since your doing me the favor by scanning it.

Thanks in advance,

Tim

[ZMANN]

Could be injectors or even a FICM issue. The dealer has been good to me with these items.
