Having Issue With My Japanese Spi


Best Answer mnr47 , 12 August 2021 - 02:49 AM

It's been awhile and forgot to update here.

 

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.

 

- The issue was my wheel bearing.

 

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.

 

- The issue was my fuel pump, it shuts down when gets hot. Once I install new pump, the issue solved.

 

 

I have replaced all the vacuum hose with samco silicone type, new rear fuel filter as well. The temperature is fine as well.

- 3mm samco hose

Hi There,

 

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.

I had that "engine jerking" problem - I discovered that the coil was shorting/arcing on to the cylinder head!

 

Or perhaps the fuel filter is clogged?

Curious to know the size of the samco silicone tubing you used...or part number. Thanks

that temp looks low, what thermostat is fitted, are the hoses  3mm/4mm? get a diagnostic tester something like an ACR4 it will show what the sensor readings are and help to point towards existing problems if any
