Distributor not advance spark timing according to engine speed/rpm and making engine vibration during acceleration and deceleration. I have adjusted distributor setting with timing torch which was 5 degree according to engine manual but engine making vibration during acceleration and deceleration, when I adjust distributor 10 degree the car runs smoothly but the pick up of car is low. I think spark advance timing is not working, please tell me its fault about distributor, ECU or distributor adjustment issue. And how to check these issues.
