Sounds like crankshaft sensor is breaking down.

 

Yeah as said crank shaft sensor especially with no engine signal/rpm.
They don’t usually throw a code when they go

 

Thanks guys I’ll get one and give it a try

 

Had engine management light come on before I had chance to fix - pedal test came back with 0300 .... so looking on here changed the lambda as well as crankshaft.... couple of laps around the block seems to be all good....

Will see tomorrow when it’s the commute and a proper drive

Sorry I’ve just checked the code again as I thought why had I changed the other sensor... the code is 0030 which I was under the impression was that sensor... sorry

I'm confused, best to clarify if the code is 0300 or 0030

 

P0300 is multiple cylinder misfire and usually points at the coil pack being at fault.
Sometimes they break down with age and the heat with being placed at the top centre of the engine ( heat rises and more prone on the bigger engines)
See how it goes with the crank shaft sensor.
Why did you change the o2 sensor?

 

The coil pack was only changed a month ago... along with plugs.... hoping they are not faulty already?

Unfortunately after about 5 miles driving this morning it died again

 

Ok so your coil pack and plugs where changed around a month ago and you have been getting this issue around the same time?
Was a genuine coil pack used?
Sounds a little Suspect with the P0300 code

 

No it’s been since then... the management light with that code has only shown since yesterday though so you think worth investigating the coil pack and replacing that now the sensor has been changed?

Thank you!

Yes sorry!

Right so I’ve just done the pedal test again as of now.... it’s coming back with:

0300
0301
0302
0303
0304
0314

Looking like the coil pack then? Would that reflect the symptoms previously mentioned, cutting out in idle even after driving a few miles etc

 

It could well be the coilpack,was it a genuine/oem pack or a cheepy fitted ?

 

It was a cheepy unfortunately so need to start their... I shall try that then....

Once changed will that wipe the engine man light to know it’s worked so to speak .....

Thanks, an I appreciate the replies!

 

Which light is on,the emissions or car/spanner ?
a bad enough misfire will affect the emissions quite quickly and can kill the cat,i've also seen ecm's spiked with bad coil packs.
I'd make sure the replacement is a Delphi (fitted oem),they are available for sensible money nowadays.

Sound mate....Cheers

It’s the engine management light once car starts.

Once it dies / like it’s stalled....the oil light, battery, car/spanner and the engine management light appear

 

Hi.... I’ve got a delphi from euro car parts and changed that.... started drove 50 metres stopped at end of the road and system shut down again

 

P0314 is code that stands out ( non specific cylinder miss fire detected )
Usually a sign of a lean mixture due to a manifold air leak or an EGR fault etc.
I think some more investigation is needed before replacing any more parts .

 

ok then the next step would be to rule out excess crankcase vacuum,leave it ticking over for a few minutes then try removing the oil cap

 

Thanks.... after I remove the cap is their a time to leave it for / sound to listen out for etc?

 

If there's excess vacuum,you'll find it difficult to remove the cap

 

The car was cutting out straight away so couldn’t get that far.... A friend has said to check the EGR valve, connections and give it a tap, sounds strange to me... but it has seemed to work as it started ok then and I’ve just drove it 5 miles without any issues....

So would this need replacing / cleaning properly... I’ve seen a few things on here with different solutions so what’s the best if you guys have experience?

 

Alright guys... unfortunately I'm back with I think the same issue if anyone can help

So after changing the EGR valve and driving for approx. 1400 miles the engine light has come back on (im only posting here as I think it might be connected).

Using a mobile code reader its giving me the code P0171. It drove ok then it died as I slowed down this morning after driving a few miles. IT started back ok and allowed me to get to my destination.

I'm completely bamboozled now..... Long shot but if anyone can help... im hearing apart from things that I have already done would be maybe a carbon clean or check/clean/change mass air flow sensor but I'm clutching a bit now....

Hi, longshot posting on here after such a long time but did you ever manage to get this sorted? I’m currently having the same problem on my Astra where the engine is cutting off/ stalling when I reach low speeds but have no engine light on and even the garage can’t seem to find what is wrong with it, thanks!
