Hello everyone,
I recently started to tacle my high idle issue (stock 2.0 FI). I have read many of the posts about the vacuum line and idle.
I did replace all vacuum hoses with the AA kit, which I thought was very nice. I know things are properly connected but my idle is still close to 1500rpm. I disconnected the vacuum line going to the deceleration valve at the air filter end, plugged it, and the idle came down to 1000.
The deceleration valve is properly connected with the side port going to the air filter.
Is the valve supposed to partially open when idling or is it supposed to be completely closed?
Thank you for your input
