| In two words FUEL FILTER.

| Thanks, but why not all the time ?

| It could be a dodgy fuel pump or pressure relief valve.

A friend of mine with a cavalier had a tiny hole in his fuel pipe,
just where it joined to the fuel pump. The pump ended up sucking
mostly air. The car actually stopped completely, but maybe you have
a mild attack of the same thing?

| Re fuel filter why not all the time. The filter gradually clogs and
hence the fuel flow through it becomes gradually less. The maximum flow
is at high revs under load e.g. motorway cruising and then
acceleration and will gradually get worse.
To further test theory, if you have a mechanical fuel pump it will have a
vent hole to release pressure if you listen to this or cover with a finger
tip you will find it venting. Usually you can hear it at tick-over as a
sort of whistle but depends how bad filter is.
How do I know this I spent a week with the same fault on a Mazda
recently.

| 961.6 | Intermittent Flow Meter. | GIDDAY::HOOPER | Customer Service (Hardware), Sydney | Fri Feb 16 1990 00:50 | 11 |
| <Electrical Connection>
A similar sort of thing was happening to my Commodore (3 litre EFI), and
eventually I cured it by just removing and replacing ('reseating'), the
electrical connector at the 'air mass flow meter'. This is the
apparatus which meters the amount of air flowing into the engine,
and it is situated just after the air filter, flow-wise. I suspect that
there was a bad connection at this connector. Several garages were
unable to fix the fault, mainly I suspect, because I was the only
person who actually observed the problem, it being so intermittent.

| 961.7 | Could be water in the fuel | GIDDAY::GILLINGS | a crucible of informative mistakes | Fri Feb 16 1990 10:01 | 19 |
| I agree with .1, first check the fuel filter. It is possible that you've got
some water in the fuel tank which is being trapped in the filter. This tends
to be intermittent because the filter will trap the water and then release it
in a globule. Once the glob has gone through (cough, splutter, hop) it takes
a while to fill the filter up again. It may also be due to the design of the
fuel tank and location of the outlet. The water may sit below the outlet and
only get into the system when you turn a corner quickly or go up or down a
hill of a certain gradient. You may not notice any cause/effect because it
takes time for the water to reach the engine. To confirm this diagnosis,
remove the filter and empty its contents into a jar. If there's lots of
water in it you may want to get your tank cleaned out.
Some years ago I bought a new Suzuki Swift. The FIRST TIME I filled it
I managed to get a petrol pump which had just been "cleaned". The result was
a 50-50 mix of petrol and water. The car would run for about 2km before
exhibiting the same symptoms as .0. I would then have to empty the filter
and start again. I managed to get the cost of a new tank of fuel having the
tank cleaned out of the service station (after much hassling around).

| 961.8 | Check the fuel! | CURRNT::PREECE | Atonal apples and amplified heat... | Fri Feb 16 1990 13:24 | 8 |
| Look out for water in the fuel !
I used to have an SRi of the same vintage, and had to have the
injectors replaced after I got a load of wet petrol. They went
rusty ! (No, I didn't believe it either, but that's what the man
said)

| 961.9 | Known problem ? | VULCAN::BOPS_RICH | You never give me your money, ... | Fri Feb 16 1990 13:37 | 7 |
| I seem to remember that early CDi's (and perhaps SRi's) did suffer
from an intermittant fuel injection problem exactly as yours does.
(Sudden loss of power). Vauxhall garage should know - try ringing
one, they might be able to tell you whats wrong and quote you a
price !!

| 961.10 | Food for thought | SHAPES::DOUGLASSP | Course you don't get wafers ! | Fri Feb 16 1990 19:39 | 10 |
| Thanks for all your suggestions. I'll be checking them out on Sunday
and let you know.
Rich - I had spoken to several Vauxhall dealers before I posted the
Base note. They all suggested the electronic injection system was
playing up and I should check the connectors all round to see if any
were loose or corroded etc I'll be looking at those last of all if
the other ideas turn nothing up.

| 961.11 | The answer | SHAPES::DOUGLASSP | Howling at the moon | Tue Feb 27 1990 13:41 | 15 |
| Well now ... I know it's been a little more than a week but I wanted
to wait and see if the problem recurred.
I didn't get to check the fuel filter last weekend. All I did was
break the airflow meter connector, blew into it, dusted it and put it back
together again. Voila !
After 10 days without the problem happening again, I am cautiously
optimistic ! If it does start again, I'll check all the other things
suggested here but until then .. fingers crosssed.
Thanks for all your thoughts.
Paul.
