Vt stalls and squeels

[craigaus]

I was heading up a right turning ramp to enter on to the freeway i heard a squeeling noise then when i backed off the accelerator the motor stalled.
I got out and checked under the bonnett and couldn't see or smell anything unusual i thought as the sound was like a slipping fan belt, but the fanbelt was fine and not broken or burnt in any way.
I started the car it was labouring to start up then it started the idle was hunting and rough then i reved it and it ran normal.
I went back to home without a hitch.
Any ideas as i was turning left i think the pot in the fuel tank wasnt an issue as i had 1/2 a tank.

The only time I have heard this was on my VP commodore, when the air intake was severly blocked the engine would squeel, (like a slipping fanbelt) then stall.
not sure if the squeel was from a sensor indicating low air flow. or the engine trying to suck air in through gaskets.
the only way I realised this is what it was, I started the car and blocked the air intake with my hand, and sure enough it squeeled, I removed my hand before the engine stalled.
maybe you could try this, take off your air filter cover, start the engine and using a clean rag block the intake with the rag, try using a rag that won't get sucked up the pipe.
the engine will no doubt sound as if it is starting to labour... see if that replicates what you heard.

Well thank you very much i didnt even think about that lol ive thought of everything else but now you have mentioned that and thus the car hasnt been serviced in a while i think your on the right track as its happened to me with an older commodore .
Will let you know how i go thanks again for your valuable insight.

New air filter should help your fuel economy slightly too... maybe more than slightly if it's THAT blocked.

Check all your idler pulleys. One of them might have a seized bearing so it is either spinning on the bolt that holds it on or spinning inside the pulley. Plastic pulleys fly apart when the bearing seizes but metal pulleys could last a few hours.
