Sucking air from somewhere

Hey y’all I put a k and n air filter on my truck and now it’s suckin air from somewhere I though it was the air filter so I put stock one back on and its still doing it I need help it won’t let me attach a video but it only does it when the motor starts to rev up from low idle thank in advance

 

Sucking air from somewhere else? Interesting, how can you tell? Did you clip the stock air box down properly?

Video would be great.

 

Did you put the air box lid bad on right? There’s 2 tabs on the bottom side

 

Should change your thread title, you've been here awhile.

Help is reserved for those that actually need help IE stuck somewhere, broken down, etc.

 

Good point.

 

That was my first thought actually, broken down or stuck.

 

Put the nozzle on a can of brake clean. Spray around the intake hoses etc and see if the engine revs up.

 

I'll read other gen sub sections but that's it; I clicked this thread from the home page though thinking someone could be stuck. Could be in my area, or in an area I know someone could provide assistance.

 

Changed title sorry y’all never thought bout title and yes everything is tight it’s coming throttle body somewhere idk if the flapper could be sticking somewhere gonna year into it Saturday

 

Sounds like something that got disconnected for the K&N install didn't get reconnected

 

That damn K&N.

 

It didn’t start till till after a week of installing it truck started running like poop

 

so just so everyone is on the same page. you just changed out an air filter and now things dont run right.

 

I put stock back on and still sucking air

 

check for rips, things disconnected, etc in the hose / tube that runs to the throttle body.

 

I'm guessing pcv or whatever that hose is on the backside.

 

We knew they sucked, and here's proof...

 

Check hoses and clean MAF.

 

Haha good call....I assumed he meant he installed a K&N cold air intake but maybe he did just mean an air filter

In that case I'd check the MAF...might have gotten oiled up and screwy from the oil on the K&N filter. Though I dunno why that would cause a high idle but who knows

 

Look first where the human was last method has a stunning success record.
I agree with not only triple checking airbox fitment and clamps, but also seeing if MAF is gummed up with silly air filter oil.
