Hello everybody, my fathers F150 with a Eco boost has cut out then went into limp mode with the big wrench on the display twice now. The first time he was in his yard not going fast at all. The second time he was on cruise going down the highway. No codes were set either time and it runs fine after you re start it. We've decided to do plugs because it's prolly due anyways. Has around 75 000kms on it. So just with some googling it sounds like it could be the throttle body or condensation in the intercooler. Does this sound right? Are we on the right track? Where should we drill the 1/16 hole in the cac tube? Any feed back would be greatly appreciated.

 

Definitely do the spark plugs as they are only good for 30k miles. Use motorcraft sp534 gapped to .030. Next drill the 1/16" weep hole in the lower driver side of the intercooler.
This will protect the truck for future. Your issue right now does sound like it is electronic throttle body related though.

 

Thanks for your reply, so far we've replaced the throttlebody with a new Ford one and drilled a hole in the intercooler. Zero oil or moisture came out but it can't hurt. Anyways plugs are next as soon as his retired budget allows. Lol. NGK plugs ok? Or do they need to be Motorcraft?

 

They have to be the motorcraft plugs. These are very easy to do yourself. Verify the gap is .030. The ecoboost is very finicky with plug gap.

You are correct that the weep hole didn't drain anything. It will only do it while driving.

 

Sounds good. Motorcraft it is. Thanks

 

So just incase this helps somebody in the future replacing the whole throttlebody assembly has fixed the problem. Just a heads up.

 

So did you change the plugs and drill the hole and still have the problem? Just want to understand what steps you completed before replacing the entire throttlebody assembly.

 

We drilled a hole but found no moisture in the intercooler and haven't changed the plugs yet. Replacing the throttlebody seems to have fixed it so far.

 

Thanks. Reps sent for updating your post. Drilling the weep hole and replacing the plugs is often a cure-all for most issues according to some members. Sorry to hear the throttle body was bad, but glad you got it resolved
