Hello fellow Wira drivers, I'm having a problem possibly faced by all the old Wira drivers... My year 2000 Wira auto 1.5 engine shakes and dies easily.

Brief descriptions:

1) When car is idle(N), engine shakes badly and is on the verge of dying, usually it dies when I change to D and step on the pedal too heavily, I have to accelerate slowly otherwise it will most probably die.
2) The engine doesn't shake when the car is moving, only when you slow down and idle.
3) To my experience of driving this car the engine shouldn't shake when I change to (N) when I stop at traffic light etc, but now even when it is on N it still shakes badly and seems like it is going to die.
4) Problem seems to be less serious when I turn off the air conditioner, although it still shakes a lot even when gear is on N, which did not happen last time.
5) I have noticed a slightly sluggish acceleration too.

Anyone experienced this before? Any solutions?

Sent to service centre and they said my Wira is using a newer version of throttle body which cannot be cleaned(?)... and they suspect it might not be throttle body problem, in the end, changed my engine mounting (full set), any comments on the prices:

1 x Exhaust Bullet RM 90: No idea what's this for.
1 set of plug cables RM75: He said this is stuck and spoilt/no longer functional which will affect acceleration, indeed my car accelerates faster now.
4 units/1 set of engine mounting RM330 (included all labour fees): Really solved the vibration issue... doesn't even vibrate now when changed to D and step on brake to hold the car

Took my car to service today to fix the throttle body/ISC jerking/engine dies off problem.

At first the mechanics said they can't find the required hardware to replace the gears inside the throttle body, asking us to change a whole new TB for RM950. So I googled around and thought this is throat cutting price and rejected. Then he offered to do some modification to the throttle body to fix that problem for RM180 and my mum accepted, the car is back now and seems to be okay until now, no more jerking at all. On the receipt:

Mod throttle body with Denso Vacuum Valve - RM180 (anyone has got any experience about this?)
Silverstone M3 tyre - RM180 (overpriced?)

No idea about the tyre size but I suppose that is overpriced too.

Oh shit... I heard fixing the problem that way (Toyota FICD?) will cause more long term problems

The hell man I sense something wrong already when he said he wanna do modification...

Btw that is including labour fees...
