Smells funny to me... Did you ask him why...or why he didn't check
with you before incurring the additional cost?
Generally speaking, except on April 1, it's not necessary to reprogram
the PCM for a throttle body clean, just clear the parameters it has
learned while running with a dirty tb. That's all we're doing when we
disconnect the battery during the clean.
I agree with everyone else. All I've done or ever heard of being done was to disconnect the battery for at least 30 mins or the time it takes to takeoff the throttle body and clean it. Was this a Dealership or just a local mechanic?
