Hey there. It sounds like your throttle body is bad. Check to make sure it’s clean and not sticking. Clean the throttle body if necessary and check for loose connections with the throttle body connectors, too. Since you said that you replaced the wires, make sure you have all of the connections properly seated and in the right place. If you need to have this checked, a qualified professional from YourMechanic inspect the rough running in order to have this properly taken care of.
