There is a fix for the condensation build up in the intercooler!

I'm going to say bumper to bumper. Because a wheel bearing is a bumper to bumper item. And some transmission parts are bumper to bumper.

Furthermore since the issue has already been documented on my platform, it is a known issue! Also, Ford dealerships used to have the option to good will warranty, but things have probably tightened up since then?
If you are correct, which I doubt, then it becomes a moot issue! My question is NOT what is or is not covered under warranty, but WHAT is the true fix and not a band-aide!
Sorry if I come off as a little snarky, but this ain't my first rodeo! I suspect that I was working in the dealerships before you were in grade school, as I have turned in my share of customer warranty work in the past!

All I'm saying is go get the TSB done if its COVERED under warranty. If you still have problems Get a full race cooler and a custom tune. Even if you worked in dealerships before I was in grade school doesn't mean you are a great mechanic.....

I am just somewhat hesitant after seeing the picture of the new OEM CAC cross section that German EB posted on another thread?

Ya I think you are talking about Wagner intercooler. I would go full race if anything.

I have studied numerous posts on this issue. Some skeptic that moisture was the cause. I have experienced the severe engine misfire, bog on acceleration but have never had any warning lamp come on and never a stored or pending code in the computer. The bog was so bad at times I was stuck in the wrong lane trying to pass and could not. The bog will occur also after exiting the freeway and trying to pull out onto a secondary road which is really dangerous as it first accelerates then just
bogs and leaves you in the middle of the road.
I have driven the vehicle with a fuel pressure gauge to monitor fuel pressure and a scanner to verify that there was no issue with the electronic throttle control system. When the symptom occurred there was no malfunction recorded by the computer. There was no change in the throttle position, fuel pressure, intake air temp, engine temp, mass air flow did change but this was due to lower engine rpm. The oxygen sensors showed a rich condition - water entering the combustion chamber kills the combustion so raw fuel enters the exhaust.
To find out if moisture build up in the intercooler was really the cause
I cut a piece of cardboard to cover approx. 45 % of the intercooler and drove the vehicle for another month and tried to make the symptom occur under similar conditions. The symptom did not occur over a 4 week period. Before that it occured almost every week. After 7-8 weeks it has not occurred again.
I have noticed little if any power difference and no difference in fuel economy. The fuel economy has even increased slightly.
I do still experience the slight chuggle in 6th gear on light acceleration but this occurred before the modification.
I had planned to start reducing the size of the restriction until the symptom returned and then adjust the size to prevent the problem from returning.
I find it disturbing that as extensive as Ford claims to have tested this powerplant that they put it on the street without addressing this issue.
At some point during the testing it had to rain and these symptoms had to occur. It is also odd that it took them more than 2 years to figure out that a slight reduction in the intercooler capacity could correct it.
I guess I will trade my fancy cardboard for a plastic deflector and a pcm update. My experience showed me that this fix should have little if no impact on performance. My guess is that they are probably not deflecting air from as much of the intercooler as I have. The engine performs well with a pretty large amount of the intercooler covered.
I hope other owners will find this information helpful and my advice would be to have the deflector installed. If you still have the symptom you can always make it larger with a little cardboard and zip ties.

xaoc25 and others ... I have a ScanGauge II which monitors TPS ( Throttle Position ). I was flooring it Saturday on the expressway. I noticed that the TPS would not go above 55%. Before I have the PCM update fix, I could swear that the TPS percentage would go to near 100. I think the engineers finally figured out that they needed to restrict the air flow.
Can someone else confirm this?
Does 5Star or Livernois tunes remove this restriction?
