you guys know any walnut blasting on northern johor or melaka area?
wanna to clean throttle body or intake.
because sometime on traffic light, on auto hold D1 or N
car will vibrate with fixed interval, slightly giving it a little throttle/accelerator vibrate will gone for now.
at first i tot rpm dropped too low, but after observation..rpm still same.
changed sparkplug like 5K mileage ago, so i suspect throttle body or intake dirty now.
issue: it doesnt happen on every traffic light stop, so reproduce kinda hard as it random appear

update on these situation.
just now replaced alternator pulley, it seem like the random vibrate 'solved', drive 40~50km stopped few traffic light seem like the vibrate almost not exist(back to normal feeling)
100% not sparkplug as i switched to original plug weeks ago and not solving that vibrate.
tldr: alternator pulley fault.
will update after days of use.
Edit:
I did notice my right side engine mounting (driver side) sink slightly, probably one of the reason the vibrate i mention previously transfer into cabin
still observing until i change the timing/fan belt..will change that mounting together too.
about 1 more week after replace alternator pulley.
that intermittent vibrate gone. so yes, if any one experiencing similar vibration.. don think...just replace that pulley
