FAST 90mm TB....idle screw intake was installed and tuned a month ago
idled rock solid at ~850-900rpm or so
recently went through and painted the valve covers and cleaned up the engine bay.
now i have a sudden high idle (1100rpm)...and hanging idle when i come to a stop with the clutch in (~1500).
checked the pcv system and it doesn't seem to be the issue.
then i touched the idle set screw and it turned, and the idle dropped to what it was supposed to be.
i turned the screw with my finger!!!
is that normal? is there a "lock screw" or some means to keep the screw from changing? i figure i must have bumped it while under the hood.
seemed odd...any suggestions?
