ok , 2000 to 2002 models are known as grenades for their tendencie to have engine problems . if you search this site you will find lots of information about this and also about how to prevent these issues from re-occuring . there is a system called NADS , which is a series of modifications that you can make that should stop it from happening again as well as to allow the engine to perform better and in many cases more fuel efficiently as well . i strongly suggest you read up on it . it is worth the effort.
