K&N and P1130 issues on a '02 Pathfinder

[AzPathy]

I've got an '02 pathfinder that I installed a K&N FIPK on 300 or so hundred miles ago, yesterday it threw an SES light. Had it scanned and it came up as P1130 code for the swirl control valve.

My mechanic looked it over and said it has something to do with a vacuum line going to the swirl control vacuum check switch. Basically his diagnosis was that after I installed the K&N there was less vacuum in the intake tube due to the free flowing filter, and therefore the 2 vacuum lines that are connected to the lower side of the intake tube are not functioning correctly. He suggested taking a T fitting and connecting it to one of the vacuum lines on the VIAS/SCV solenoid and hooking the vacuum line from the SCV check switch to that as opposed to the intake tube. Does this make sense? Or should I just pull the lines and clean them out. The code hasn't come back so we'll see. Thanks.

The codes back and I also noticed my cruise control won't work. It will turn on, but won't engage. Apparently this is related to the lack of vacuum. Anyone have the same problem or a solution? It's not a super big deal, but having the light on sucks and cruise control is nice on the occasion.

I can't see how these problems would be caused by an air filter.I used a K&N filter for 2 years and never had any issues.The only problems I've heard about are related to oil contamination on the MAF sensor from too much oil on the filter.Heck, I've driven around in my truck and cars with no air filter in them at all, and never had any issues.I mean, no air filter is about as free flowing as you can get. I'd get a second opinion if I were you.

Thanks for the reply Buzzman. When you say K&N filter do you mean a drop-in, or an intake? Just curious, that will make a big difference due to the different sizes of the intake tubes and placement of the vacuum lines etc. Everything he said adds up, I would've come to the same conclusion, although it would've taken longer. We'll see sometime this week, Im going to fiddle with it.
