OR is there something I can do to fix this ?

Car has new plugs and wires. I cleaned the K&N filter about 3 months ago.

And ideas ??

Had the exact problem with my C4 tried everything ended up going to a dealer. They got in right on the first try. ICA valve Hope this helps

What year is it. 2004's don't have pcv. They have fixed orifice system. At least my '04 does. Probably should not speak for all.

His profile shows that he has a 2000. I have a 2001 and it has a PCV Valve (same as you can see in his photo in post #37). I have changed mine twice, but never had any issues with mine - just maintenance.

So your problem was a bad PCV Valve?

I'm guessing the pcv valve was partially bad due to the hole in the vacuum hose.
