2002 Honda Accord.. high miles.. was fine when purchased used.. 200,000 kms. Went for highway drive... after about a year of owning it as I had done prior. speed..hit 100 kms and it's like the engine shut off.. loss of power..needle bouncing. . So slowed down and got of highway. Now it is only a car to and from work 3kms rounds trip. ..but it is giving some weird actions. On idle its real rough almost choking . .and even acceleration it Rocks and bucks fore and aft seemingly.... mechanics read the error code but can't remember as it was a year ago. It's now worsen any explanation for its bucking and rough idlem. PLEASE INFORM ME.. would like an idea before I bring to mechanic. ..

Thank you
