1998 Buick Century 3.1L hesitates badly on acceleration. This issue has just starting occurring and I don't have a good idea what could be wrong. I tried cleaning my egr valve which was recommended to me but that is not helping. The car hesitates on slow and fast acceleration when it reaches 10 mph, 20 mph, 25 mph etc.
