Hope someone could advice me on the issue currently i am facing. There are 2 issue. My mini is japanese SPI with coil pack(rover black engine). Below are the issues:
1. My car vibrates on braking. The vibration can be felt towards the pedal itself. Initially i thought it would be my disc rotor so I have done replacing my entire brakes with new disc rotor, new front pad, rear new hydraulic pump and new brake shoe. I even serviced my front calipers and replaced all the oil seal in it. After all was done, When i tested the car, the vibration was still there. I managed to diagnose it and found the vibration from left wheel.
could it be my wheel bearing? As i noticed there is slight play on the left wheel.
2. The car idle fine at 900rpm with and without a/c, But once awhile while driving the car, it will jerks as if not enough fuel. Then when i turn off the engine and start immediately it will fire up without issue and I will be able to drive few more KM until the jerking comes again. This only happens once awhile. not always.
I have replaced all the vacuum hose with samco silicone type, new rear fuel filter as well. The temperature is fine as well.
