i have a 03 f150 and it the 4.6L and i have a k&n cold air intake and it seems like i have no power. it feels like a 6 cylinder could beet it i was just wondering what it could be. my air filter also make this weird nose like its not getting enough air or something i have never herd it before

 

No power in your ENGIN ???

 

it seems like my pickup has no power

 

Start with a tune up. Plugs, wires, fuel filter. Any SES lights? Check codes. EGR valve is a common issue with poor engine power.

 

no ses lights do u know anything about my intake??

 

Does it make a whistling noise? This is just the sound the CAI makes. Check to make sure the filter is clean and you should have no issues with that. I'm telling you a simple tune up will do wonders.

 

its not a whistling noise at all its a really bad noise but i will do the tune up and see what it does thanks

 

What kind of noise is it?

 

idk how to explain it but it shakes the whole intake...kinda like a grinding noise but i had someone look at it and they said its just the air coming back out of the intake but he really didnt know

 

Did you recently put the CAI on( meaning did you have the stock set up on and then put the CAI on) and now you have that sound? If so the CAI will make a different sound. As for the power loss if you did recently put the CAI on did you disconnect the battery for about 15 mins so the trucks computer could adjust to the new changes. Everytime you do anything different to these newer engines you have to disconnect the battery for awhile. Just an idea.
