idle problem solved

I had posted earlier about an idle problem with my '98 Escort and I got some great suggestions. But after cleaning the fuel injectors, replacing the air idle control and checking for a vaccuum leak I still had a high idle. It turns out the problem was with the PCV valve. So, is anyone else is running into idle problems, you may want to try pinching that off to see if it makes a difference. It's a cheap fix.
