howdy

My 2010 f150 fx4 5.4l is acting up. When i hit the gas it makes a vacuum sound right in front of the driver side under hood. ANd it wont accelerate quickly as usual. made an appointment with dealer. ANy ideas? I have no mods on the engine

 

When you opened the hood to check this out, what did you see?

Thanks

 

Everything seems normal under hood. Nothing different than normal. I couldn't press the gas and be watching to hear the noise so I couldn't tell if it did it then. But sounds ok idling.

 

Sounds like some type of leak? Have you checked the air filter to see if it's clogged up?

 

I havnt opened that up but where the heck is my transmission fluid dip stick!?

 

A piece of insulation has come apart from the fender well and is infront of the air box inlet opening

 

You don't have one that is easily reached.

 

Ya kingfish I felt stupid for not being able to find it lol thanks.

Jhunt.
Did that happen to you?

Anyone else this issue?

 

There is a dip stick, but it is next the the catalytic converter under a screw on cap.

 

Jhunt you were completely right! It's A's good A's new now. Thanks

 

What???



A piece of insulation?

explain this...

Got a pic?

 

Evidently this has become a common issue. I've heard of it a half dozen times on the forums over the past year.

 

glad its fixed

 

Jhunt........... that is impressive.

 

Can we get alittle more info on what happened? I'm having similar issue with my 2010 4.63v
