Hi!

Hoping for some help as always. I replaced the air filter in my Boxster with a new K&N filter. I read afterwards that some people have some problems with it, hmm.

Anyhow when I pulled the old air filter out there was a lot of debris that went everywhere - dust, stones, twigs. I used damp kitchen towel to remove it all from the air filter compartment and made sure there was nothing left.

I gently lubed up the filter tray ribs like the instructions say and placed the filter in.

But now, she idles between 600-1000, going up and down. And if I let the revs fall too fast like at a traffic light, she stalls.

Has anyone had this problem? Maybe I didn't put enough lube and there's an air seal problem? Wanted to research before I try to fix.

Thanks so much as always :-)

John

P.S. DAMN she is faster now she doesn't have an old filter in her. After 4500 revs it is a pleasure.
