Is there a way to tweek the cruise control on these truck ie when I press resume it takes it a while before the cruise starts to control, on older vehicles you could adjust the vacuum to make response quicker.

 

Could be a sticking cruise control disengagement switch.

See link below, near end.

 

CC on a 6.0L is all in the PCM. Meaning the only adjustment would be by programming.

 

Which leaves very few suspects....

 

Guess I'll learn to live with it, darn this truck has been great, 58,000 miles and replaced the FICM on warranty and repaired a small oil leak under turbo. Life is good right now!! Doing all the recommended upkeep and monitoring temps.

 

yup all in the pcm, it is what it is.

 

The cost of the cruise control switch is less than $20, and I replaced it in about 45 minutes of work --- and got a bonus brake bleed / fluid change out of it..

 

I have always hated how slow the ford C Control is to respond to input. After I drove the new Dodge with the toggle lever on the right side of the steering wheel (like older BMWs) I really hate my dog-slow set-up. -Mike
