If there isn't a noticeable engine mis at idle, most likely it is caused by the throttle body and iac being clogged up with oil and carbon. A fault in the ignition or fuel system will almost always cause a miss that will be noticeable and in turn cause a low idle. Taking off the intake tube and spraying some throttle body and intake cleaner in the throttle body should clean the blocked air passages and fix a low idle problem.
