Hey guys I have a problem. Every time my rpms are between about 800-1500 the truck makes a worbling noise. I have a K&N cold air intake which may be making the noise but im really not sure. Any help would be greatly appreciated.

 

thats normal its the IAC closing

 

okay cool so how do I fix it?

 

put stock intake back on.... there isnt a fix for it. unles u put some elaborate muffler on it

 

so does that mean my k&n is broke? and if it is can buy a new one or will it still make that noise? also if I put the stock intake back on will it stop making the noise? I really like the K&N but i just want my truck to be back to normal. Im really goiong to miss that extra noise an power though. Maybe if I can replace the intake I'll get an AF1 The weird thing is that everything I have read about people having problems with the IAC is their car or truck is stalling. Mine doesnt stall it just makes a noise between those rpms and when it idles at around 600-700 rpms it doesnt make the noise but once it hits 800 rpms there is that noise again.

 

That noise is NORMAL when the stock silencer is removed. If you want to use an aftermarket intake, you are going to have to live with it. NOTHING is broken.

 

really? huh ok well as long as nothing is messed up. why did it just now start to make the noise?
