gray smoke w/ loss of power upon deceleration

[a2aa]

Hi Folks!! 2005 f250 powerstroke-- 107k miles.. started this weird symptom of losing power and creating light gray smoke coming off the ramp. If I baby it on neutral, it'll recover. What is it??

Sounds like an EGR problem to me.

Start by cleaning the EGR valve.

THANKS for help sir, but where is this item located?? Pls Excuse my ignorance.Now I can see where the decreased power might be coming from. bUT what's causing the smoke?? Thank you

The smoke comes from the coolant being burnt or thats what I think. The EGR valve is located on the intake manifold.

It was the EGR.. ordered the o-ring kit yesterday and fixed it last night. YOU GUYS ARE AWESOME! Had to "yank" on it quite a bit being that it has 107k miles and I believe this is the 1st time it was done. Soaked it in some "solvent" for about 30 mins...Major angioplasty in my opinion. It was caked on there pretty thick! I attached a 1/2 PVC tubing at the end of my shopvac and vac'ed away in the EGR hole. Ran beautifully this morning! THANK YOU!
