“I recently purchased a 2005 model Mustang Gt from jim skinner honda in dothan alabama. The vehicle has a significant water leak into the passenger floorboard and into the smart junction box area. The water penetrates into the wiring harnesses and box itself.

When raining the vehicle typically experiences electrical ghosts of various sorts. …”

A week before the 18,000 mile service a check engine light came on, it was discovered that codes p-2004, p-2005 were present and a TSB from Ford, # 06-7-10 were present. This is a problem that is known by Ford, but unless you are under warranty or have an extended warranty, Ford will not help. The problem is the motion control valves and throttle linkage. …”
