Well first of all im new to this site!!!!!!!!! https://www.f150online.com/forums/im...es/biggrin.gif
well i just bought a 2006 Mark Lt a couple weeks ago still with the warranty and what not... here are my questions... when i start the truck and i sit in park the truck seems to have a rough idle? it idles around 500-700 rpms... no serging of any kind...when im driving its fine, but then after it seems to warm up some, it idles a little more rough, you can feel it when your at a stop or in park?? the person that had the truck before me seemed like they didnt take that good care of it.. so i have been giving it a lil tlc....

my second question is... when im a light on a hill and i go push the gas and take my foot of the brake the truck seems to roll back more then it should??? could that have something to do with the idle? is that normal? my other trucks that i have owned if at light on a hill and you take your foot of the brake to the gas they didnt move that much, it kinda feels like its in neutral?

thanks for all the help in advance!!! thanks!!!!

take it to the dealer and tell them about the rough idle, there may be a newer PCM calibration available to address some issues like that, otherwise they may dfind something worng with it.

As for the roll-back its the nature of the torque converter, heard it before and aside from a higher idle there will be no fix for that problem. If your idle is within spec then live with it.
