My 92 Lesabre has the Service Engine Soon light on. It gave me code 26. I know the ECM runs two circuits of with 4 components each circuit. Does anyone know which ones the "A" circuit controls. My buick's engine shakes when idling and especially when accelerating. Any help will be appreciated.:banghead:
