VZ V6 Executive Alloy Dies when turning or getting to OT and Fans Kick on

[Cali Speed]

Hey there, was wondering if anyone has had this problem.

Have a VZ V6 Executive Alloy that I bought just recently honestly hasn't been looked after at all [bought real cheap]. Been having an issue where I would take her out for a drive and she'll be running fine but all of a sudden it will cut out and die when I turn left/right. Lights still on dash but just dies, but she'll start up and will die if I try to turn again.
Even noticed now when it gets to Operating Temperature and the fan kicks in the car either dies or idle drops. Also drops idle when A/C is on

- I've replaced the MAP sensor thinking it would be that. Seems to idle somewhat better than before but still dies when turning.
- I've pulled the air filter and housing and given a clean.
- Cleaned throttle housing.
- Removed pcv hose and did notice it was very dirty full of gunk, removed it and gave a good clean and pcv also had gunk tried cleaning as best as I could. (Think PCV has a slight leak as revs picked up after spraying near it with brake cleaner)
- Also going to attempt to do an Idle Relearn whenever I get the time. Not sure if it will make a difference


Is PCV leak/PCV Hose related to this issue or am I completely off. Would love to hear suggestions! Still apprentice learning the trade

How good is the battery or alternator? Starts OK?

Do the pcv remove/clean/drill out then replace the vac hose or at least shorten it for better connection if possible.
Cost very little.

Tested the battery and that passed.
Alt was charging good too under load

Any idea if the one on the left bank is removable? Or fixed? Ive looked around and apparently the one that sits on the Right bank is an orifice than can be removed. But the left is fixed? Correct me if I'm wrong.

Will still look into what you said though, thanks

PCV is on back of drivers bank. Valve on passanger bank is can't remember, purge I think, but someone will tell us
Of course if passanger bank valve is leaking vac then repair vac hose, also look at 90 degree fitting at front of plenum chamber, these crack and leak vac as well.
In fact chase any vac leaks as a start cause they is cheap to fix

Will check it out for sure and update if anything changes.

Cheers again !

How did you check the battery health and charge?

If it was a battery/charging system problem, one would think once the car died, it wouldn't fire up again without a jump start

Just thinking aloud with that one too, so might be wrong

Remove/clean/refit all earth points.
Clean with sand paper emery cloth file etc etc
