It could be a few things, most likely you need to change the fuel filter or the spark plugs. It can also be the quality of fuel you put in your car, the cheap stuff rots the tank and sends shards of rust through your engine.
Could be Electric Power Steering or Engine Position Sensor.
YES HAS A TIMING BELT ON THE LEFT SIDE OF THE ENGINE INFRONT of the altenator and waterpump
Misfire detection.
The firing order for a 1989 Holden Barina, which typically features a 1.3L or 1.6L engine, is 1-3-4-2. This means that the cylinders fire in the sequence of the first cylinder, followed by the third, fourth, and then the second cylinder. Always refer to the specific vehicle manual for confirmation, as variations may exist depending on the engine type.
The Holden Barina typically features a non-interference engine design, which means that in the event of a timing belt failure, the engine's pistons and valves are less likely to collide, potentially preventing severe damage. However, it's always advisable to consult the specific model year and engine type, as variations may exist. Regular maintenance and timely replacement of the timing belt are still crucial to avoid engine issues.
It is not recommended that an amateur replace a timing belt in a Holden Barina. One would have to take everything off from the front engine cover to just remove the cover. Then, there are marks on the crank pulley that needs to be lined up to replace the timing chain. A licensed mechanic can help you with any questions.
I'm not a mechanic / technician but I BELIEVE if the fuel injector is restricted so that the proper air - fuel mixture is not getting to an engine cylinder , that an engine cylinder misfire can occur ( that is only one of the causes of an engine cylinder misfire )
its the throttle position sensor
normally the coil pack
Cylinder misfire. Possibly failed or failing engine mounts.
Misfire, bad spark timing, bad engine mountings.
