My 06 SC 4x4 now has 23k on it. Since new it has had a bog or stumble under slight acceleration. Is this common with 5.4's or do I need to see the dealer??

Thanks!!!

 

Mine has been at the dealer for 20 days for the same problem If you get it figured out, let me know, because they can't seem to!

 

Now I'm nervous...

 

High likelyhood it's electronic throttle lag.
What they are athorized to do about it is unknown at this time.
Keep us posted.
There is a way to fix this but you will need to spend money for custom programming to effect the fix.
Ask the dealer to look into a PCM update if they don't know enough to look.
Good luck.
