So....... my thinking that water was getting into the electrical system and causing the ignition to miss behave is wrong !!!! These are my symptoms car starts first time mostly after start up revs bounce up and down between 2 and .6 little bit of gas and it settles when driving some times revs cut out and nothing happens when you press the gas some times it starts and idles and the gas pedal dose nothing. here's the really good bit whilst driving along the road and any speed the revs cut and the only thing I can do to bring them back on again is to click the ignition back one click then back again this starts the engine again and off we go any one had similar to this ????? I can't keep driving like this it's dangerous and silly the revs cut at all speeds and some times the car won't start again coming back from vockys the other day it cut out in th efast last of the M1 a few times them in the best of all places the very tight off slip for the north circular which is just over a trucks width wide sat there for a few mins with hazards on then it started back up. Answers on a post card thanks gents

Sounds like the painful process of checking wiring by the sound of it Certainly check the key connections for continuity and clean up any earth etc. Also some extra focus around the loom connections for the DBW, and ign module stuff Will be something trivial just the worse things to pin down Had an issue on a turbo many years back and that was earth on the ecu related Good luck DG

Throttle body or pedal or the wiring in between. Loom of Doom springs to mind.

Got to love the vx loom of doom

Could it be EGR related? When that sticks it can play silly buggers with the revs... The cutting out, in particular at speed, reminds me of a problem I had on an old Fiat Uno many years ago. It turned out to be the fuel filter. Changed that out and all was good again!

Deffinitely loom of doom type symptoms. Check the spring/latch in the terminals as well as the general cleanliness. Mine had weak terminals and gave these symptoms. Swapped the terminals and its behaved for a while now. If you need terminals give me a should, I can look back to find which ones you need for the blue / black plugs. (blue plug for TB connections by the way)

[Mike (Cliffie)]

Mine did exactly this and it was the loom of doom. I just used contact cleaner spray and hey presto.

Think someone needs to come up with a kit of new connectors to replace those shitty ones in the bay.

[DarrylB]

Loom of doom - after my fun and games I'm now a pro I have a spare Throttle pedal, a spare Throttle Body, Op-comm and and can take those plugs apart in minutes! BVSD - im staying at my Bro's this weekend in Watford...I can always take parts and tools with me if you fancy nipping over for a bit of troubleshooting? PM me

Yeah, I'd thought that. I can obtain the ones in the header tank plugs but the ones for the throttle and pedal are only available from Delphi and you have to order 1000's.

[Andrew aka Stuwy]

my boss had this and it was a faulty fuel pump relay... just an idea

[Uzi Lover]

Crankshaft sensor or fuses or relays or loom of doom or fuel pump. Very similar problem. Was crankshaft and fuses

If you want to try a new pedal ive got one you can have... plus lots of other parts that vocky stripped off, so if you need anything then ask Vocky if ive got it as i dont know what half the things are

Just replace with a few sure seal connectors or similar.


Neil, Once I track down one of our crimp tools at work I'll see what can be done to help.

Thank you

all this switching off whilst driving is a bit naughty
but the worst is when you pull away from the lights and it then cuts out
and car behind nearly joins me in the cabin !!!!!!

once again thanks for advise and offers of help

[NickB787]

Any mods to your injector loom? I had some bad joints on mine for a while caused me real pain, I only found them in the end by running the car on the drive and giving the loom a gentle tug, I found the bad joint/s that way when it ran rough, just a thought

[mcewanslager]

Had a similar experience with the relays in the boot. But mine only seemed to happen with extreme g force from flooring it or taking a corner. Think its the seimens relay which isnt expensive from ebay. £40 from vaux. Worth a change.

So....... my thinking that water was getting into the electrical system and causing the ignition to miss behave is wrong !!!!

These are my symptoms

car starts first time mostly
after start up revs bounce up and down between 2 and .6
little bit of gas and it settles
when driving some times revs cut out and nothing happens when you press the gas
some times it starts and idles and the gas pedal dose nothing.

here's the really good bit
whilst driving along the road and any speed the revs cut and the only thing I can do
to bring them back on again is to click the ignition back one click then back again
this starts the engine again and off we go

any one had similar to this ?????

I can't keep driving like this it's dangerous and silly
the revs cut at all speeds and some times the car won't start again

coming back from vockys the other day it cut out in th efast last of the M1 a few times them
in the best of all places the very tight off slip for the north circular which is just over a trucks width wide
sat there for a few mins with hazards on then it started back up.

thanks gents

You could always set it on fire and claim off the insurance

But legally speaking, I didn't tell you to do that

do you think I'd get enough back to buy another though
I'd also need to get the special vocky engine out of it too.

I have thought of that too

I'm off on holiday tomorrow so when I return I funk around with it some more

hopefully it's just a simple fix
