gsi misfire

[planetc]

I was a tester in the 90s, and the easy way to remember what to test which way was that the k plate onwards had a cat test and earlier stuff was plain co and hydrocarbons. It may well be different now though as I haven't been a tester since 2001

[cavaliersri]

not sure if mine needs a cat or not.i hope not.lol
iv still not sorted the miss yet.
i tried a mass airflow meter from my pals and unplugged the lambda but still the same.was worse when i unplugged the lambda.
had my mate check the fuel preasure and he says its ok.

can it be the dizzy itself?

[cavaliersri]

iv been told that aswell as the distributor my car has an electronic dizzy somewhere.also my rad fan has been bridged and is running all the time.could this cause a misfire?

[planetc]

No. You have substituted most of the likely candidates. Has your friend checked fuel pressure under load or just at idle? I would swap out the pressure regulator and injectors/rail to eliminate and following that you are probably looking at a mechanical fault like an air leak or sticky valve. Check all the pipework thoroughly for splits or cracks.

[cavaliersri]

if i unplug the hall effect plug on my dizzy while the engine is running what will happen?

[planetc]

Cows will fart in the bath and moo very loud?
I'll give you time to think about this one yourself because you can probably figure it out without help, lol.

[cavaliersri]

just a quick update.
the misfire was down to the dizzy.got replacement and all is well.

got another question tho

what does this unit do.it seems to be power steering related
and where can i get a replacement from coz mine is leaking.

[Gaz]

4x4 bulb

[gsi pie]

as above that runs the 4x4 system

do you have the 4x4 light on dash? or have you pulled fuse 19?

[cavaliersri]

the 4x4 light is sometimes off and sometimes on.
when the light is on my windows dont work and when the light is off they do

[cavaliersri]

dropped the gsi off today for mot tomorrow so fingers crossed.

[cavaliersri]

got gsi back from mot test........FAIL.

needs nsf ball joint worn.
fuel leak at tank.(pipe)
front and rear registration plates honeycomb effect.
ns headlight aim too high.
nsf brake bipe insecure (not clipped in)

not bad at all considering it was stored in a garage for 6 years.
retest booked for friday then taxed and on the road.....yahey.

[cavaliersri]

hi folks.im back to nip your heads again.
my 4x4 light was staying on.i checked the fuse for power today and theres no power goin to it so i gave it a feed and now the 4x4 is working great.
the problem i have now is the light is on when ignition is on.when i start the car the light flashes continuously while the engine is on and when driving.
has anyone else experienced this.

although the car is driving in 4wd now the light flashing is doin my head in
