5L stalling on base idle

[Keesh]

Just have a lil drama that i cant fault, last night after a short drive, im sitting at the lights and the vq stalls. Crank it, it starts then i let it back to idle and it cuts again. This morning i start her up, misses for about 5 seconds then comes good.. After another trip i pull into a carspace and drop it to idle. And it cuts again. No splatter just strait out.. Im thinking its something playing up at running temp?

what mods?

Close to stock 304. Has vs type coil, new dizzy cap, trigger module replaced 12months ago
Fuel pump is priming but dont no if theres sufficient pressure.. I took it for a drive this morning and it was fine, just after the 20 min trip it stalled at idle

First up Id do an error code check to see if any error codes are showing up.
---Checking your Computer for Faults (VN - VP)---

First thing i did.. No codes

Whats the voltage like from the Battery and Alternator?

Next Id check for vacuum leaks.It might be that a vacuum hose has come off somewhere around the engine..There is also a vacuum reserve tank under the left front guard up in behind the bumper.It looks like a black plastic ball,check its vacuum line.Ive seen a few of these vacuum hoses split or come off here, as its all exposed to the bottom of the car near the wheel.Also the brake booster can be another cause of a vacuum leak.

Just drove it back 20 mins stalled once. Now i can get it to stall once..

14 v under acceleratuon but drops at idle, always has had a bad voltage regulator

[soop]

I reckon that will be your issue then. I needs to be a minimum of 14votls. Alternator is probably giving up.

[Brett_jjj]

If its stalling one minute,and not the next, its unlikey to be a vacuum leak then..

Have you checked the Idle air control valve (IAC) for correct operation or any crap in the passageways that air bleeds through at idle?
