Flapper mod question
I've been searching all over for this problem but can't find anyone with the same issue. Just did the flapper mod but ran into some issues, I followed the flapper removal instructions on rouge site. Plugged up the line that goes to the throttlebody. Now she idle low around 900-1k and wants to die out. I adjusted the idle screw to 1300-1400 to compensate and it runs pretty rough and stumbles. So I'm scratching my head and double checking what I've done. So I went ahead and took out the plugged screw from the vacuum line that goes to the throttlebody and she runs fine. Smooth and idle back at 1300 engine temp 180.
My question is , does the vacuum line to the TB have to be plugged?
Did I do anything wrong?
I left the flapper cover in place but only took the vacuum tube out and cap the opening ( read some where that just taking the vaccine tube off the flapper remained open) everything else is off and plugged.
