I know I've said it a hundred times, but mine was jumpy and chugged a bit and i did a PCV delete, cleaned out the intake with sea foam and totally cured it! Other than that check your air/fuel filters, vacuum/fuel lines and a new coil/plug/wires did help.

What year is ur car? Mine is an 86 an I had an actual pcv valve with a vac line going my pcv (witch is in your valve cover) to the back of my throttlebody an I capped the line on my TB put a k&n crankcase breather in its place. I gained some vacuum an got a steady idle. Newer mustang just have a tube going from the valve cover to the intake. Same concept though. Breather on the valve cover and cap\plug the other end.

Exactly. And how I run sea foam thru is I unplug the vacuum from the brake booster(plug it with your thumb fast tho, your car will die) and slowly slip the vacuum hose into the sea foam bottle and just let it sip it up
