1984 buick regal 3.8 carbed v6. Intermittent

\015 1984 buick regal 3.8 carbed v6. Intermittent ''sevice engine soon'' light. Code 53 appears when jumping A and B terminals. That is egr system failure. New egr valve, egr solenoid, thermal vacuum switch and new vacuum hoses . I cleared the ecm, but light comes on again, but not continuous. Light usually comes on at freeway offramp then goes out when pulling away from intersection. Any ideas?\015 Posted / edited by AnonymousUser on : 22-04-2019
