A bad cable will prevent the throttle from closing properly. The second
return spring should be able to keep that tab counter clockwise against that
stop. The two springs back each other up in case one breaks.

Subject: Throttle tension spring... Purpose?

That long spring that goes from the air plenum to the tab on top of throttle
return spring doesn't seem to do much on my stock 2.1. Should the spring
return the tab to fully counterclockwise position?

I'm trying to fix an intermittent problem where the throttle keeps the RPMs
high with foot off the gas pedal & the clutch down or in neutral.

Every time I check it while engine is running fast, that tab is full to the
clockwise. RPMs fall to normal when I rotate the tab to the counterclockwise
position.

I've cleaned the throttle body and lubed the return spring. Do I need a
shorter spring? I'd like to understand what that long spring should be
doing.

Thanks,
