I put a K&N cone air filter on my 3.o v6 and the check engine light came on. The same thing happend when my brother put the fipk kit on his tacoma. Why?????

 

Did you make sure you hooked everything back up and checked all connections? Made sure the clamps were tight?

 

it just clumped on to an adapter plate. The adapter plate bolts to the adapter that goes to the stock airbox. It used the stock air tube so i didnt mess with any sensors or anything???

 

Get a pic of your engine...

 

yea we need a pic... you could have still knocked something loose...

 

Did you buy these components new or used??? Did you oil them before you put them on??? If you did clean your filter and MAF and dont oil as much. If you bought them new then oiling is not necessart as they are preoiled.

 

how do i attach a pic to a reply????

One other thing, you have to have it on a website or hosting service. It cannot be linked to your computer to appear on the site. If you need one photobucket works well.

 

when i put my k&n intake on, i reset my computer by unhooking the battery for a second.
Did you do that?
If not i would try that and keep us updated.
