hi guys , sorry im not a native english-speaker , so hopefully the below descirption will make sense for your guys. as one of corolla fans , I really need you help , appreciate!! my 2008 Corolla AUTO just done 5,500km , ten days ago it had engine oil(gold castrol 5w-30) and oil filter (Repco) change by my friend who is a toyota mechanic. but after that , my car starts shaking especially when I am waiting at traffic light or gear is at "P" position with engine running , and engine noise is louder than before . I checked oil level indicator which is normal, and rpm stays normal as well my friend says alright , but shaking is really annoying me in past week , i just wonder Have your guys ever met this problem before? is this because i dont use toyota genuine toyota oil and oil filter or could be other problem ? could please someone help me out with this issue..........many thanks !
