Re: PCV valve for TPI

[WEG1192@aol.com]

I am having a problem getting my idle speed to drop low enough to approach 
the desired idle RPM as shown on my scantool. The IAC motor shows 0, and I 
have a 4000 ppm speed sensor hooked up and it appears to be accurate. The 
only way I can get the idle speed to drop from 900 to 700 RPM where I want it 
is to pinch off the PCV valve line. Are the TPI PCV valves anything special? 
Are they smaller orifices that won't let as much air through? Thanks.
