Hello, could anyone tell me how to reset my idle, when i first start it in the morning it's up around 1200 to 1500rpms and after it's warmed up it's at 900 to 950rpm that seems to high. What shouldit be set at? Also on top of the 3fe intake manifold right in front of the EFI emblem there is a large screw head. Anyone know what it's for? Thank you
Randy
