Almost same problem, pero automatic yung akin. When in D and stop, nagba-vibrate yung engine, although pag umandar na eh nawawala ang vibration, nawawala rin when shifted to N or P. Had it checked out, inayos yata yung engine mount, then cleaned the servo, cleaned and adjusted the spark plugs (inusog yung bato). Bawat ginawa nya eh nag test. Nakikita ko naman na unti unti nawawala vibration sa mga test nya.
