I have a 2012 Ford Transit connect 2.0l the van has close to 180000 miles on it, and it seems to idle sort of rough, changed spark plugs, air filter, and oil it helped but I’m convinced the injectors are dirty from wear and tear the van is a work van used for landscaping. My questions are when replacing injectors do I have to do any type of programming after? And what brands can I use instead of motor craft if that’s what ford sells? I don’t have time to clean the injectors have to do it in one day and only on a Sunday.
