2002 Ford Thunderbird Premium 2dr Convertible w/Removable Hard Top (3.9L 8cyl 5A)
After 11 years
one Ford dealer new the answer. Our car
motored at 25MPH (as if in cruise control ) ever since new, so it was
very hard to stop . There are lots of them with the same problem . You need to change the Idle air control, about $200. Ford calls it IABP
The dealer is Sunny Side Ford in Holden Ma. Scotty service manager .
