While driving, the vehicle began to accelerate on it's own. When brakes were applied the rpms sky rocketed. Turns out it was a broken cruise control module cable that would cause the throttle to get "stuck". At the same time it was also bogging out and shutting itself off while driving. The check engine light remained on throwing a p071? code which is associated with O2 levels. This turned out to be a broken "breather hose" which is connected to the air intake. Both parts have proven to be extremely difficult to track down. After replacing the "breather hose", ccm throttle cable, and also an O2 sensor the overall cost for parts was $300 and labor was $300. Thankfully no injuries.
