tickover

Sorry about this I'm so embarrassed! I ran out of petrol, I know all the warning lights and a petrol gauge what more do I need, down to laziness I'm afraid, "will get petrol next time I'm out" type thing.

Anyway now "she's" paying me back by refusing to tick over, I've put 2 gallons of petrol in and it starts fine but refuses to tick over and it's as if she is blocked in the exhaust and is raring to go but is spluttering and is back firing. I'm very apprehansive about taking it out on the road as I feel it will just stall. although it does sound like it needs a good "clearing" out blast. Before the petrol incident when you put your foot down quickly it gave a cabbage smell in the cabin, literally as if someone had stuffed a cabbage up the exhaust. A weired post I know but any ideas?
 
I would disconnect the battery for a few mins, then start it and go for a good 20-30 minute drive - on the roads you normally do. The system adapts itself to different conditions and it is possible it adapted to a low fuel condition. Don't let the car idle - you must drive it.

Failing that, it could be dirt from the bottom of the tank getting into the proceedings. It may clear with fresh fuel, if not a dealer check on the filter, injectors etc etc may be needed. The cabbage smell is one I don't have a foggy on!
 
Maybe there is a cabbage stuck in the exhaust. Has anybody checked ? I once found a dead rabbit on top of my R5 Turbo silencer. It ponged for ages until I found it.

 
Definately no cabbage up the exhaust, I even made sure me and the lady didn't eat cabbage for a week!![:D]

Will try disconnecting the battery - seems strange but thanks, I will give it a go.

 
Graham,
Disconnecting the battery then reconnecting it means that the DME has to re-map itself. Good excuse to have to take the car out.

Cheers,

 
there was a cabbage smell in my car on the way to work this morning, however I had a lot of garlic, red meat and roast veg for my dinner last night..
 
I've got a feeling that when you have sorted the problem .... the cabbage 'thing' is going to linger for a while (the jokes that is!)
Enjoy your drive ......
 
Hi All,

Thanks for the comments and jokes so far (need something to keep my humour up). I'm afraid disconnecting the battery hasn't worked, now the car won't even start, I left the battery disconnected for around 5 minutes then re connected but no joy. I carried this procedure out twice but with no success. The car appears to want to start but doesn't continue to run, a classic symptom of not enough fuel (this is not the case anymore, there is plenty of fuel in the tank). How difficult is it to remove a spark plug, I would like to see if it's getting "wet" or is "dry". I have just read the manual and it's on about removing a number of items before taking a plug out.
Thanks for your comments slider but the cabbage smell was prior to the incident of running out of fuel, I mentioned it as the car appears to be "blocked" in some way and won't run, initially, smoothly, now not at all.
Any help would be really appreciated.

Thanks
 
Hmmm odd. Have you checked the fuel pump fuse?

I would remove the air filter, make sure the air-flap is not stuck, and try again.

Have a look around the air intake area for any loose connections, or sensors not sitting correctly.

On the plugs - not sure that would help but you should be able to remove the one nearest the oil filler cap area if you have the right plug spanner - should be one in your tool kit.

I assume from you text that the engine turns, catches a little and then stops - is that correct, or does it never catch???
 
Hi,

Thanks for your very quick responses this forum is brilliant for that and the helpfulness is fantastic. Yes the car catch's for a few seconds then stops, so I don't think the imobiliser is the problem.
Surely by checking the plugs is wet I can confirm fuel is getting to the plugs and not being blocked in the system (fuel pipe, carbs etc)?
It's a horrible feeling having a sick car in the garage, nicely polished but wont start (and occasionally smelling of cabbages!! [;)])

Thanks again for your help so far.

Graham.


 
A "cabbagy" smell, akin to a "rotten eggs" smell often means a faulty catalytic converter. If you have one, the lambda sensor may be giving false info to your ECU, possibly causing your fault.

Kevin,

The usual culprit here is the Idle Stabilation Valve. It's a small cylindrical "thingy" right on top of the inlet manifold, dead centre above the engine. It's an electrically operated valve that bleeds air to the inlet manifold when the engine is on idle. It's operated by the DME directly and is driven by pulses to achieve very small movements in quick response to the engine conditions.

A common problem is that the all-too-often oil overfills can result in excessive oil mist being recycled to the inlet manifold which in turn accumulates in the ISV and makes it "sticky". If you remove the ISV and clean it out - carefully - with some brake cleaner I suspect your problem may be solved.

If your problem is more specifically experienced when the engine is only cold it's possible that you could have aproblem with the cylinder head temperature sensor. This tells the DME that the engine is cold and the DME effectively engages the "choke". No sensor means no choke and the engine will not reliably idle until it's warm.

Hope that helps.

Regards

Dave
 
thanks dave, car has just been serviced so the oil issue sounds possible, however just taken it for a longer run and seems to be better when properly warm -so could still be either! will have a look at the stabilisation valve first

thanks
