I'm having a hard time with drilling the hole. I've only had the hesitation problem one time in 3 years, and it was about as wet as possible, up in the clouds in the mountains, after driving for about 4 hours in those conditions. I just have a hard time believing this would be a good thing long term. If it was, why wouldn't ford make a tsb with the hole or incorporate it into subsequent designs? Just doesn't make sense to me.....though I want to believe it works. Little help here to swing me please.

I drilled a 1/8 hole in mine... a whole buncha nasty stuff came out. While it has made the hesitation and sputtering BETTER, it hasn't solved it. If i drive to work, the truck sits all day, and I go to pull out on the highway/merge, i still get a bit of misfire.
I've decided to save up for a new IC, Piping, Can, and some other goodies.

Have you done plugs? Throttle reset?

Hi, OK so you drill a hole in the intercooler to drain water. Intercooolers get hot/warm with pressure. What's to prevent cooler, damp air to be drawn back into it as it cools off after the engine has been shut off? Then this damp air being pushed back out of the weep hole like as if you have a problem, but you created it by drilling this hole in the first place. The weep hole needs a check valve.

Its been explained before, numerous times. Its under positive pressure.

Secondly with the hole drilled at idle and most light part throttle the engine is operating in vacuum state. This allows unmetered air to enter the intake. This will introduce air to the engine that's not measured by the mass air flow sensor post the air filter. The result will be a leaner fuel mix than the ECM is attempting to command. How much? It's only a 1/16th hole. If there was a second mass air flow sensor next to the MAP sensor at the throttle body/manifold one could measure any delta.
I think the biggest concern is drawing in unfiltered air, but with the hole being so small that probably isn't an issue unless you regularly drive offroad or live someplace rather dusty.

Forks your lift
just drilled my weep hole. A watery oil mixture came dripping out.. I reved the motor a couple times and it sprayed out then. Letting it drip out now. Going to hopefully do the throttle reset here soon

I pulled my intercooler while doing other repairs and stood it on end over night and nothing came out and I never had the studdering. I drilled the hole while it was out just because the of the stories I have read. After my first drive to and from work (30 miles) and it sitting overnight I could see stuff had drained out of the hole. All that moisture/oil has been going into my engine the whole time and not settling in the intercooler. While minimal enough not to cause misfiring it could contribute to the carbon build up on intake valves where ford says the only fix is to replace cylinder heads (but valves can be cleaned instead).
