Any Idea on why my fd would sputter at idle, but run fine under any amount of load?? The engine has 24k on it, and runs just fine under WOT, no smoke or anything!

Also, it is idleing at 1500rpm

1500rpm idle?? https://www.nopistons.com/forums/pub...DIR#>/ohmy.png



You need to lower that!! Adjust the screw on the Throttle Body to around 750-900rpms. Should fix the problem. https://www.nopistons.com/forums/pub...IR#>/bigok.gif

if you have some kind of intake leak, like a popped off vacuum line etc, it will make the idle go high. Since you say it is sputtering at this high idle I suspect something has come off.
