Advices on Hyundai Getz problem
Recently, my car 9-years old Hyundai Getz have started to add new problems
Vibration - when in D or R, and hold the break will cause it
Heavy/Slow - the break LED appear and seems quite sensitive when breaking, acceleration is slow
I already changed the spark plug twice because it have misfiring problem previously, now new problems arise which not sure what's actually is. I heard it could be idling control but not so sure about it.
Can you suggest and advice what to check on? Thank you.
