Engine vibration at low idle speed in a Daewoo Matiz can be caused by several factors. Common issues include worn engine mounts, which fail to absorb vibrations effectively, or an imbalanced engine due to misfiring or irregular combustion. Additionally, a dirty or faulty idle air control valve could disrupt airflow, leading to unstable idling. Checking these components can help identify and resolve the vibration issue.
The engine speed sensor on a Daewoo Matiz is typically located near the engine's crankshaft or flywheel. It is often mounted on the engine block or transmission casing, depending on the specific model and engine configuration. To access it, you may need to remove some components or covers. Always refer to the vehicle's service manual for precise location and removal instructions.
because the ecu compansates the engine speed for the load..as it does for electrical drag etc .Gone are the days of engines stalling under load!
It's on the gearbox, you need to get under the car to access it. It has a 3pin plug.
Clutch wear can be told by noticing no wheel spin when the engine revs are higher than they should be for the speed you are going. Make sure your foot is off the clutch. Thrust bearing wear on the shaft make a sound when you engage or disengage the clutch. You may also feel the oddness in the pedal when the noise occurs.
Check the motor mounts
The speed of the vibration changes the pitch of a sound. A higher speed of vibration creates a higher pitch, while a lower speed of vibration creates a lower pitch. The size of the vibration does not directly affect the pitch, but it can influence the volume or intensity of the sound.
They are feeling a speed related vibration.They are feeling a speed related vibration.
it seems your car engine support gone, needs changing.
Not many F8B Altos came out 5 speed, in fact all 800cc models in New Zealand were 4 speed. I'm not sure if anything was available in Australia or even ex Japan as they're getting old. There are Alto clones made in India as Mauritis(?) and also Daewoo Ticos that were based on the Altos followed by the Daewoo Matiz which had a F8C injected engine 5 speed. Problems with the gearboxes from these later cars is that they may not bolt straight up to the Alto engine, they are cable gear change and have different size shafts on the CV axles. As the top gear on the Alto 4 speed is already an overdrive (0.9 to 1), I just compensated by fitting larger tyres (155/80x12s instead of 145/70x12s) to my CB91/SB308 Alto that I'm converting from automatic, I've dismantled several cars for donor parts and I've got plently of spares, Matthew :o).

At high speed vibration usually its tire balance. Have your tires rotated and balanced.
Are rims bent, check body bushings or check engine with scanner for variations in running
