boley jadi ignition coil dah blow, sebab N42 ada empat....kalau satu kong memang gegar je enjin

most likely is your ignition coil... get it check asap.. Don't try to drive it long distance it will definately damage your engine..

usually i dun think anyone will change the ignition coil kalau tak rosak, the cable also got possibility. ask your mechanic to spare u a second hand ignition coil to test

Bro, my advise is don't take the risk to drive ur car with that
condition. Pls tow ur car to the nearest mechanic ...

It is recommend to change all 4 coils when one one of them is faulty.

Faulty coil or spark plug or HT cable can be easily detected by pulling the plug one at a time.

When you unplug the HT coil, the one that does not effect the engine speed would be the culprit.
