Running rich code? Most likely its an O2 sensor showing that, which is a symptom not the problem. Most people that work at parts stores have no fukkin clue what they're talking about...

crappy multec injectors are leaking down when you kill the engine! its dumping fuel into the cylinders fouling the plugs. its a common issue with the 7.4 due to factory shitty injectors!! the raw fuel coated the 02 sensor causing it to read rich. its all the injectors bro!! get the five-0 replacement injectors for it! it WILL solve all the issues!!

Where would I start looking for them at? Parts catalog or local performance shop?
