Hello,

I was hoping someone could help me out. The other day, I was getting on the freeway on ramp when I felt a power loss. The check engine light was immediately illuminated. I took the truck to Auto Zone, and the code that showed was P0299, indicating a turbo under boost condition. The advice was to replace the wastegate vacuum hose. I've been putting in a lot of effort, searching everywhere online and on YouTube, but I'm struggling to find the location of this hose or what it even looks like. Does anyone know where this is on a 2013 Ford F150 Eco Boost?

When I checked YouTube, I found a few videos about the pressure relief valve. So I took mine off and found that the diaphragm had a hole in it. I went ahead and replaced it, and my boost came back. However, I have what feels like a misfire when I initially step on the gas for the typical stop lights and stop signs. I don't have issues when I am driving at speed.

I heard drilling a weep hole in the intercooler or adding a catch can might help. Or this might be as simple as changing the spark plugs. Any help would be appreciated.

 

How many miles on your truck and when was the last plug change?
DO NOT DRILL A HOLE IN YOUR INTERCOOLER!!!
Have you cleaned your MAF and MAP sensors?

 

it has 160000 miles. No I haven't cleaned the MAF and MAP sensors but I first thing in the morning. As for the plugs, I don't know when they were changed last. I have had the truck for 3 weeks or so and they were on my list to change out this weekend.

 

Get the codes run again. If you have a miss it is likely stored as a pending code without a check engine light and the code could point you to the exact cylinder with the problem if one exists.

 

Sounds good. I will check it right now.

 

I Cleaned these this morning. Not too dirty. Still getting that delayed throttle response. Only in stop and go situations.

 

I just checked and the only pending code was the P0299. No current codes.

Thanks for the video. I replaced the pressure relief valve already. There was a hole in the diaphragm. The boost was restored but I still have the delayed throttle response on stop and go situations.

 

Does anyone know where the wastegate vacuum hose is on a 2013 Ford F150 Eco Boost? This was the suggested part to replace.
