Achen, thanks for doing the math and trying that. I hope someone with the chronic problem follows suite. I didn't do the calcs, but know intuitively the leak won't be enough to matter.

I don't think the low-point bov will work. The condensation is forming during long periods of constant speed. I.e. the bov will not have opened in a while when you suddenly apply throttle.

 

Hi everyone. brought back from the USA in the Russian truck mileage 120,000 mile platinum. I'm at a speed of 50 miles per hour tremor occurred. I changed the spark plugs was gone and tremors. Gorgeous traction at all speeds. Nice truck. http://youtu.be/yML52lUD3uM

 

Mine did it a week or two ago. It had been raining, was cruising along on the freeway, added some throttle to pass a Chevy and it did the shutter. Took me a second to realize what it was because I still had passing power. I was due for an oil change the next day so I mentioned it when I went in. They played clueless and said maybe it was the traction control. I said no, pull the computer codes. They did and almost 2 hours later they said there were indeed some codes that matched a tsb and they would order the parts and call me the next day if they were in. Next morning they called, back to the dealer for another 3 hours and I was good to go. Tech said he replaced the intercooler, added a diverted of some sort and reprogrammed the computer, so far it hasn't happened again but it hasn't rained again yet. Hopefully it won't happen again.

 

Got my truck back last week after the new CAC. It still "chugs" a little at idle when first starting cold, but after a few seconds it clears up. Noticed no reduction in power (like some others here had stated) while driving and I did notice that the slight hesitation was gone while accelerating quickly. The big test was pulling my 24' enclosed car trailer, in the rain, with my 66 Mustang inside. I floored it at least 3 times and the truck had plenty of power with no hesitation or shuddering, etc. So far, so good!

 

Ith as been non stop terrential rain here in OK lately, and I have not had the shudder or loss of power as of yet. I have given it WOT entering on the hwy several times to see if it would do it and it hasnt. My truck only has 2k miles on it though. My dad has a 2011 SHO and he hasnt had the shudder or loss of power either. I figured if it would happen it would happen to us being in eastern OK which is very humid. Keeping my fingers and toes crossed.

I asked my local Ford service guy if anyone has come in with the problem and he said 2 that he knows of.

 

Has anyone thought of this .... Could the moisture in the CAC be coming from air intake? I thought semi's had a dryer on the intake to make sure the air was dry. With driving in the rain for a few hours, there has to be some moisture getting past the filter as the turbo pull it in.

Sorry this might be a bit long, but want to share.

And, I'll admit I'm not about to read the 158 pages/1576 posts here.....

However, I had ZERO stutter/hesitation issue as most attribute to the intercooler ingesting water UNTIL last Friday (5/31/13) and WOW.... I now understand why others have said this is a very dangerous .... potentially deadly problem.

Here's the lead-up:
Left house at 330AM from Lake George, NY en route to Norfolk, VA. AM temps were chilly at around 45 degrees F.
About 3-ish hours into the drive, we stopped for fuel. Temps had risen some, but still not hot or humid by any means.
While pulling away from the station, nothing seemed odd. Then we began to enter the on-ramp for the NJ Turnpike...with heavy AM traffic.... one hard push on the accelerator showed otherwise.... I'd swear I was driving a WAY over-carbed classic V8 that was flooding itself to almost the point of stalling. I mean the stuttering, popping, hesitation was so bad the truck would hardly move.... and the more I tried to get it to move, the worse it got. Remember, we were merging INTO fast moving NJ Turnpike AM traffic....so I was waiting to get slammed from behind as I couldn't get the truck to do anything. I actually had to let off the pedal completely and let it coast for about 2 minutes (which seems like forever in situations like this) while horns were blowing as cars went around us. And I seriously mean I had to NOT touch the pedal as each time I did, the truck would pop/hiccup/stutter and slow down. I was finally able to lightly give it some gas and get over 25 mph and then get to 30, then get to 40.... but if I gave it too much, it would start the scenario all over again.

Well, it did finally "clear" itself out and drive "normal" and I did not notice any other signs of stuttering or hesitation, but my mileage (which had been hovering around 19MPG at 80 mph all highway) DROPPED off to 13/14 for the rest of the trip to VA. I called my local dealer once they opened and was told that "FORD knows and says (to quote the service manager) "GOOD LUCK"" ..... Now, here's the ironic part. After just under 34,000 miles with no problems, I get this situation for the first time. And I have had the updated "CAC" done a few months ago even though I had not experienced the stutter and/or hesitation, but instead, a low speed issue experienced while going slow such as driving around a store/mall parking lot.

So..... now what ?????

 

Be sure to go to www.nhtsa.gov/‎ and file a complaint. Hopefully with enough reports Ford will be forced to fix the problem.

 

Ford thought they may have been the issue with my truck last spring so they put a new intake on it. It didnt work in my case

 

I just had the new CAC and update done. Mine is worse than before.
