-- I have a MY 2005 - i installed (i think to my regret) a K&N air intake tube with filter - the one that sits in place of the stock box (i removed stock air box) - supposedly i got an hp increase (which is good) and air induction sound is very good - but my once rock solid idle, and surgical throttle response with stock air box is gone - it doesn't drop back to idle smoothly, seems to hang-up then settle

-- my son has exact same install, on exact same car, and his throttle response, and idle are PERFECT

-- i have gone over everything, and there are no line leaks at all, everything is buttoned up nicely, and the cables appear identical (my car to my sons)

-- any suggestions ?

Vacuum Lines?

-- like i said, i really have looked.....everything is snug

Doug1627

Not snug, are they hooked up correctly? What cables do you speak of?

i have this issue with my 05 as well... i thought it was the cold weather tho. i do have the K&N drop in filter w/stock box. can anyone shine into this as well.

Just a thought, Maybe you guys over oiled your filters??? It can cause weird readings with the intake sensor, not sure of the exact name.

for my S, it was doing this before and after i cleaned and oild the filter

the Could all be snug. But not in the correct locations.
