Grey Smoke

Guys every since I have had this 08 F250 I have had problems with grey smoke every now and then. I thought maybe it was because of water getting into the fuel filters. They say it isn't but it only does it when I get on it from a dead stop or try to accerate coming on the on ramp. It doesn't have to be floored or anything. Doesn't do it everytime just about every 500-1000 miles.

I would say you are fine. Mine will blow white smoke or a small amount of black smoke. The gray smoke you see is more than likely black but may appear gray since it is not thick. The black smoke is fine. I notice mine will do it more or less depending on where I get the fuel. If a lot is coming out my truck will go into regen shortly because the filter is dirty. I went to the dealer about the white smoke and they ran tests and everything checked out. They showed me a bulletin they found that says they may have white smoke in damp or humid conditions...whatever else they said. He showed me the actual bulletin but I think it is just a way for Ford to not recall and have to eat the costs.

I don't care so much for the grey smoke its the fact that it won't accerate or down shift to get it to accerate faster.

Having more problems with this. About a good 5-10 seconds the truck seems like it doesn't know what to do. I almost got T boned about right after I made this thread. I started to go across the road and when my back tires got to where the front tires were sitting at the stop sign the truck decided it didn't want to accerate. No matter what I did. So it took me like 20 seconds to go across 3 lanes of traffic.

I have had it at the dealership 4 times in the last 30 days. They can't seem to make it do it again but as soon as I get it back from them it seems to do it. They put like 100 miles on it also. Yeah of my fuel. After the fourth time they told me not to bring it back until it does it more consistantly. They also said it isn't going to hurt anything because there is no codes. WTF I almost got T boned because it took like 20 seconds to go across 3 lanes of traffic.

Got any ideas?

At the risk of sounding like a broken record lately... does this happen mostly in the rain, after driving at a constant speed for a bit, stopping (toll booth or whatever) and then taking off at half throttle or more? If so, check this link out for more info. Otherwise, have you been keeping an eye on your coolant level? Main sources for white or light smoke are water in the intercooler, burning coolant because of an EGR failure, or rarely, regen of the dpf when not up to temp.
