The weep hole has been done across all of the model years. It has been accepted as the tried and true way to prevent any misfire issues. The folks doing this are also high, medium, and low mileage people. Most will either encounter this early on, or once they hit 40k-50k miles.
I disagree with your thoughts on this.
1. There was never an updated intercooler offered. It was block off plates and tuning which made matters worse. The active shutter system in 15+ helped, but didn't solve.
2. A lack of maintenance or driving habits does not cause the intercooler to build up condensate. Once you understand the root cause of misfire is condensate buildup, you will then understand.
The service record here for the 3.5 ecoboost is really poor. I couldn't find a service department that recommends them. Once you dive in and research the tons of data on this, you will understand.
Serious question, did you go to school?
You keep repeating the same stuff yet we've been telling you the same for months now - there is NOT A SINGLE POST ANYWHERE of anyone doing a weep hole on a 2015 or newer truck - "Ray" from this forum has gone radio silent
Show us 2015 or newer, that's all
We don't care on all your years of experience on your 2011
