Starts then immediately cuts out. - Saxperience

VeiRoN · 30th June 2014, 18:05

Hello there,sometime lately,more and more often,when i turn my VTS on it really struggles to keep idle and then dies in a second,if i keep the revs at 1000-1300 rpm it keeps running without any problems,sometime it just turn on with no issues.

I really didn't notice any issues with the idle,other than this,so i don't think it could be the idle valve.

The battery is in the boot and the alternator charges fine at 13.5v/13.8v.

Could be a dirty air filter? i'm quite sure it needs a good clean.

Any other ideas?

Many thanks.

As you say, try giving the air filter a clean and give the throttle body a clean up and idle control valve then see how it goes from there

I already checked the throttle body and it's very clean,an oil catch tank is fitted so it doesn't get as much dirt so i believe it can be excluded.

icv, coil pack/spark plugs?

VeiRoN · 30th June 2014, 20:35

Icv has been removed and it's being cleaned,the spark plugs have been changed a month ago with NGK BKR6EK,tightened to 25nm as per manual,the coilpack from what i know it's the standard one and never been replaced.

I had a problem with a breather pipe from the carbon canister. Ran fine disconnected, connected it would cut out. Worth a shout.

Might be worth you borrowing a mates coil pack and trying it mate.

Might be able to get a cheap used one and swap it over,no misfire or anything though?

Update: It's not doing this anymore after cleaning the Icv,so reassured if it was just that,i'll keep this updated in case the problem comes back,thanks for the help everyone.

VeiRoN · 7th July 2014, 22:47

It was fine for a week but it's doing it again,should i try with a brand new Icv? For its cost i could try.

Alex^p · 7th July 2014, 23:08

I had a similar stalling issue, cleaned the icv and worked for a bit but then the problem can back.
Only a new icv cured it.

VeiRoN · 8th July 2014, 15:32

Thanks Alex for your feedback.

I was thinking,could this be the battery that does not have enough CCA? (it has 360 but it's in the boot)

Try to test coolant temp sensor

Or try to use french shit method. Disconnect battery for an half hour, it helps in my case, when my sax was running on 2 cylinders...

VeiRoN · 18th July 2014, 05:39

People i need help.

It won't turn on at all now,well it did once but it's just because i've tried to wait then try to start it again the last 20 minutes.

I ruled out the possible "too dirty air filter" as it won't start even without it on,the alt charges fine at 13.8,when off the battery is at 12.2,as said above if keept at above 1k rpm runs fine but immediately cuts off as you depress the accelerator.

Is there anything i can do to rule out some other components without having to buy a new one,or even any check at all i can do?

Thanks.

What could be wrong with it? It doesn't seem to show any issues,temp stays just fine.

Alex^p · 18th July 2014, 08:26

Is it cranking or just doing nothing?
Did you try a different icv?

VeiRoN · 18th July 2014, 08:35

It cranks,starts but then immediately cuts off.

I'm still looking for a new Icv,i should have one in a few days.

D4MJT · 18th July 2014, 08:50

This will be the ICV dude, it's the exact symptoms I had last week, cleaning the ICV with carb cleaner helped for a day with mine, but went straight back to how it was.

New ICV, job jobbed.

You'll be able to keep it running with throttle, but as soon as you come off the throttle pedal it will die yeah?

VeiRoN · 18th July 2014, 08:53

Yes D4MJT exactly,thanks for the help guys,i appreciate it.

For what it's worth, as I'm reet pikey, I literally just grabbed a £12 one off eBay new that looked as if it would do the jerb, it's probably from Azerbaijan, but it's done the job a treat.

I never bothered with part numbers, as I'm shit.
