I have a 2011 Ford ecoboost it's throwing a p0087 code. The engine will shudder and have a hard start. The ford place I take it too does not see the code. I have had my fule pump raplced my fule rail replaced my spark plugs and boots replaced. My truck still has the same prob most of all when its humid out side. But also does it when I'm pulling somthing it's seems to not be getting enough fule. I have read that the hpfp needs to be replaced but the prob is not all the time and I can not leave my truck at the ford place for a month or untill I decides to want to mess up. I have also read that the CAC is working to well so that when it's humid out or I drive for a long time lots I've water builds up. I have parked my truck and seen water dripping from the drivers side under the truck right under the turbos. I did not want my truck shutting off on me going down the road and the dealer ship can't do anything bc it does not happen when they have it and they won't do anything about a pending code can someone help. My truck shudders the rpms jump then goes into lemp mode the has a hard start after sometimes a check engine light comes and then will go off once you drive it or turn off a crank up. Please help
