Limp mode
 

Brother in law has nice 7.3 about 145000 miles. Well maintained. Last year had issue where would randomly go to limp mode. Replaced all 8 injectors, valve cover gaskets, control module on fender and filters. Ran well for a while but randomly going into limp mode again. I'm scanning tomorrow, wondered if any ideas other than CPS? What else should I check? Any help is appreciated. . .
