Vs V6 Manual Stalling

[timbo292832]

I recently purchased a v6 Vs Manual
its my first manual commodore but when i go down in gears while driving sometimes it stalls
ive noticed most time it stalls when going down a hill and putting car into neutral

also when i take of the car jumps a bit
the previous owner told me the clutch is 6 months old
the car didn't stall when i test drove it

im not sure what the problem is
also when in 1st gear in high revs and switching into second it crunches
someone told me that would be the synchro

can someone please tell me what is wrong with my car ?

So it only stalls going down hill? How full is the tank? At what point of the clutch pedal does the car start moving from stationary?

What series VS?

I'd clean the throttlebody and IAC valve to start off with.

Crunch into second could be slave cylinder or air in the line-thats what it was in my mazda ute.

Ive seen the same thing happen when someones converted the vehicle from auto to manual and have not done the computer (ECU) swap correctly.

 

[Krusty2011]

yes mine still had the auto ecu in it while it was manual and would stall while shifting down

Will a custom memcal for an auto computer but comparable with the t5 box from mace fix the stalling as I am using the auto computer and have manual swapped the vs Ute with t5.
