Problem 2005 FordE450 Throttle problem

[Armysandy]

My vehicle was running great when I started to back into my driveway. Suddenly it slowed right down to a slow creep. Its been at the garage now for ten days. They replaced the throttle control module and then the entire throttle control without solving the issue. The tech seems stuck.
Anyone with a Ford ever seen this??

It turned out to be the throttle housing was the problem. They replaced the throttle sensor first with a new one which did not work. Then they replaced the throttle housing, using the new sensor but still did not work. On a hunch, the mechanic installed the old sensor in the new housing and it worked. CONCLUSION … Bad throttle housing and compatibility issue between new sensor and old housing. As reported by garage”
