Effects of HEI on Other Systems?
This question is for guys (and ladies) who have done the HEI mod. I have mine done and the engine is running great...however, I have a minor problem....the PCV solenoid is no longer working. As I am sure we all know, the solenoid between the PCV and carb energizes when the RPM drops below aobut 1200 RPM. When energized, it closes and helps the engine idle lower. With the HEI mod, mine does not engergize now leading me to believe that a signal from the Duraspark module was giving a signal to the computer to engergize it. Right now my idle is at least 900-1000 and I can't get it any lower.
In addition, the servo motor on the carb is also not working now....stays in the same position all the time. I suspect that its also related to the HEI mod.
If anyone has personal knowledge of these problems....please elighten me....
