yes go back to a truck Ford dealer who know trucks and have bays to fit them in.
They had some issues with throttle bodies and the gas pedal link or lack of .
BTW, you can buy a simple plug in $25 code reader from Walmart so you know what those lights mean and the codes they spit out. Those tools can also clear a code. Sometimes that's all I need to do.
