Have an 05 exp that we purchased used. Had it at the dealership and they changed the motor mounts and trans mount to help the rough idle. New mounts are supposed to allow the engine to move more and not feel it in inside. Well its the same as it was before they changed the mounts.

My question is anyone with an 05 or up do you feel as though the engine is not as smooth as it should be at idle? Do you feel a miss in the engine? Have you ever put the truck in park and rev the engine up to about 2K and does it feel smooth. Our expy is vibrating at 2K in park.
Im bringing it back into the dealership on Tuesday but dont want them to say that is normal for the truck cause if they do Im going to go sit in an 06 and check it out myself while im there.

Any info will help.
Thanks

 

It should feel nice and smooth. I can't feel anything with my '03 idling or reving the engine. You must have a mis or something. Can't believe they changed the mounts. Shame on them.

 

I've got an '06 and yes it idles very rough. My '01 with 100K miles on it that I traded for the '06 idled 100% smoother than this car! I haven't had it to the dealer as yet, but I assume they will tell me it's normal. There are quite a few posts on this in a number of forums. They'll release a TSB on this issue sooner or later, and when they do my car will probably have 36,001 miles on it. My car also starts extremely hard.

 

I stand corrected...there is already a TSB on this...To the dealership I go!

Engine Controls - Cold Start Rough Idle Condition


TSB 06-5-1

03/20/06

COLD START ROUGH IDLE EXPEDITION 4X2 ONLY

FORD:
2005-2006 Expedition



ISSUE
Some 2005-2006 Expedition 4x2 vehicles may exhibit an idle vibration during cold start at 1400 RPM, that lasts for a few seconds. The symptom is perceived as shaking of the entire vehicle when the engine is first started after being off for an extended period of time in warm weather in excess of a few hours, such as overnight, with ambient temperatures greater than 60°F (16°C). The issue is not typically accompanied by unusual engine or fan noise. It is independent of air conditioning compressor engagement (bumps, bangs, or thumps) and air suspension pump operation (audible hum or buzz accompanied by an associated vibration).



ACTION
Use the following Service Procedure to resolve the concern.

This is what they did. They changed the mounts under this TSB. Still idles pretty rough for a vehicle of this caliber. My 99 dodge durango idle smoother than this truck and that had a distributor cap. Mine does it all the time and there stating this is a cold start problem. Does it all the time.

 

My '05 does this as well. I'm thinking this is a 3V issue. Does this occur in the F150 as well? I guess I should visit that forum as well.

 

My 04 idles rough as well . It ran smooth as silk for thefirst 10000 miles then all of a sudden it feels like it has a misfire at idle. Of course Ford had it 3 days and said one bank was lean so they changed the mass air and of course that did nothing,so I am feeling your pain here on this issue. I also cleaned my EGR and adjusted my TPS all to no avail.One thing I did notice was that all summer it seemed to idle fine,then the past two days have been colder (60's)and now it idles rough again. Its making me want to pull my hair out but I have none left. Lets all put our heads together and solve this once and for all.

 

Anyone with any ideas???

 

I was supposed to bring it back in last week but the wife needed the car. We are taking it in next week to have them look it over. Im having them check everything.
