spark plugs? throttle body? i just dont want the motor to pop. thanks for any help!

both of those idles are way too high, it should be around 750rpms.
-there is no way it is an oil problem, unless you have an automatic trans.
-check your throttle cable and make sure it has play
-adjust your idle using the stop screw on the throttle body. get it down to 750
-It sounds like you have a problem with your iacv, If the KA has one.
