Hello been away for a while, and straight in with a vectra c 2.2 2008 petrol (z22yh)problem what symptoms would sticking swirl flaps or failing aculator cause. Car starts 1st time from cold then then dies with in a minute or soon as accelerator is pressed. Cheers ajn

forget swirl flaps...either fuel pressure regulator or high pressure fuel pump....trust me I know I have just repaired my own...oh by the way if it is the HPFP it is circa Ł398 from Vauxhall and it is a Vauxhall part...does your car have a continental pump or siemans pump fitted

Trade it for a 1.8

Only fault I heard about swirl flaps is when they drop of into the engine on beemers.
Nobody seems to know what they are for, other than to keep the workshop income ticking over....?

Diseasel Vectras have them to manage inlet airflow at various rpm. Unfortunately they are made of crumbly cheese, and therefore a nightmare...

As our esteemed panic merchant has said the real issue is the diaphragm in the fuel pump, which dissolves in cheap petrol, and why the 1.8 is a much better engine inspite of the 10-30 bhp defecit

Oh Al, your so behind the times lol. 

The 1.9 150 bhp has swirl flaps (the 120 does not) and they had a major change around 2005 which pretty much resulted in all issues being sorted. The only remaining issue is that the actuator bar gets worn with age (circa 100k miles) but it can be repaired with nice brass bits (rather than the plastic) for about twenty notes and job jobbed.

And Chris, they are used to improve the burn at lower rpm where the gas speed is reduced, the flaps shut off one of the ports into the head (effectively making it a single valve per cylinder inlet). This increases gas speed and causes the gases to swirl in the combustion chamber.....hence the name.

  that must have been the week after the engine in my '55 facelift 1.9 150 was built, as that was a horrible pos... Went really well for about a week at a time, but seemed to eat inlet manifolds never  again...

Worked with a bloke who bought a 2.2 petrol Vectra C... He couldn't work out why it was the same price as a higher mileage 1.8 in the same spec... Until he bought it it did look nice though, a Moonland Sri estate with XP

. Thanks for the replies lads, I bought a so called recon hpfp from eŁay didn't make a difference in the flat spot, uneven idle and limp mode. The car starts fine from cold dies after about 45 seconds or accelerator pressed. My original was a continetal the recon siemans. If I get it for a diagnostic check at a garage will they still be able to diagnose if the car wont idle for more than a minute or so. Could a fuse cause this. Ajn

Assuming later manifold was fitted then the issues just 'go'

The ultimate is then an EGR and DPF 'map out' in the software but not essential by any means.

As others have said it sounds like the hi pressure fuel pump, the diaphram in the fuel pump gets damaged by the ethanol in the fuel, which over the past few years has been quietly raised from under 3% to 5% the max allowed without labelling the pumps. Way to stop it in the short term when fitting a new pump depending on where you live is to use either BP Ultimate, Texaco S/U or Esso S/U no ethanol in these fuels at the moment.

However just seen your latest post saying you have replaced the pump but still have problems so I may well be wrong, anyway hope it helps and you get it sorted.

That's sort of what my neighbour said with his e39 530d, and makes an amount of sense, until comparing before and after swirl flap ectomy by seat of pants, and said he couldn't tell the difference.

....although later, much later, I do recall he had a slight complaint of the car chugging at low rpm. Mostly after his speed awareness course

[Marks DTM Calib]

Its quite noticeable, the low down torque is less and the economy takes a hit.

[05omegav6]

Those courses must be infectious

[Marks DTM Calib]

Oh yes, on the swirl flaps, try actuating a set at idle on a car with them fitted.....a very noticeable change in engine noise.

[chrisgixer]

Hmmm. I guess given the choice between some chugging and lost performance, and a destroyed engine, the ectomy wins, as his are made of plastic which deteriorates and falls apart, taking the metal flaps and screws into the bore with it.

The flap rail he removed on his straight 6 had one broke section hanging by a thread. Not a moment too soon.

At that time there was no consideration to replace as they where deemed pointless, I guess that thinking may of changed since on that particular engine.
