Broken wires at the throttle body connector is very common on these trucks & it will cause the "reduced enging power" messege on the cluster...AND set throttle body codes, Take the coils & throttle body back for a refund. Dont ever use that "shop" again either.....Scan tools are a tool just like a wrench...They ARE NOT replacement for experienced automotive technicians.

Untape the harness back about 6 inches from the throttle body. Lightly pull on each wire individually.....the one that stretches is the broken one.
