Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
The fault with your car is most likely to be an ignition coil malfunction on one cylinder, very common to 1.8.
Engine DTC will be one of P0301- P0304 depending on the cylinder that is misfiring.
I would check the spark plugs for service life as well, if they have travelled more than their recommended service interval.
Spark plug Interval is 60000km.
Hope you have had you car fixed.
