raise idle?
 

ive been having voltage problems with my car and if i could raise the idle about 150rpm it would fix everything, my engine doesn't seem to idle at the right RPMs because the whole engine like shakes at idle and i was just wondering if theres anyway to change the idling RPMs since everything on the TB is automatic

besides the throttle body idle set screw

screw it in slightly, it pushes the butterfly open

i dont think that it has an adjustable screw on it, i think its just something crimped onto the end of the throttle cable

you should first try to clean the IAC valve A black valve located on the throttle. That's the normal case of surging idle.
