Gen 3 1ggte stalls out when stopping? Help!

**Gforce6** · 10-04-2007, 08:13 PM

Ok, I hope someone can help.
When driving the car, and especially after giving it a bit of a go, when coming to a stop, it cuts out! It starts straight away, and is fine again, until it gets a serve of boost, and then stalls when coming to a stop again.
Even if I give it a blast, and then push the clutch in, it will stall. I have changed the management, coil and pump and that didnt help, so was wondering if maybe it might be the idle motor, or something to do with vacuum at the inlet manifold?
Any thoughts? Is this common? Any advice on fixing?
Thanks
Andrew

have you got a blow off valve, if so take it off and get a plumback one. or check that its not leaking.

Factory BOV and appears to be not leaking........

1g's never came with BOV's look again.

"management, coil and pump "??? Even though you could deduce most of what you were trying to say this wasnt very descriptive.
Check all your piping and your map etc. What is an idle motor, pretty sure 1g's never came with one of those.

ISCV - Idle Stepper Control Valve.
It's front of the intake manifold next to the throttle body.

6 Pin plug - Centre 2 pins should have 12v when car is switched on.
Other 4 are earths that the ecu controls.

Check that you have 12v at the center pins if not thats an issue.
If you do have power it could be the valve is dead or need cleaning.

Edit: like Rob said 1G's dont have BOVs standard. Take it off and block it .. see if it makes a difference.
