i have a 2003 ford f-350 with 125000 miles less than four thousand on new motor and pretty much everything else under the hood is new. now the issue is my mechanic has installed three sets of injectors and now on the third set, the truck runs rough until it warms up. now the mechanic is saying bad fuel is causing the injectors to fail. i have a edge evolution programmer and no dtcs come up. any ideas on why my truck is running rough on start up? thanks
