should not have replaced anything till you know the failure.

is the check engine light on??

look for vacuum leaks. idle air control may not be working. throttle body may need to be cleaned.

what were the codes?? o2 codes do not mean they need to be replaced, just that they cannot do there job.

no coil pack as it will not cause only an idle issue.

did you check what i requested??
