You dont think there's a computer problem do ya? Have you tryed resetting
it? If so, Ask the dealer if you can get a new computer to see if it pings
with that... These new computers dont break to the point where something
will stop working.. but will cause some funny stuff to happen....
(My old computer made my truck cut off 4 times before it completely died,
took about 6 months too)
Sounds like it could be the problem... =/
