Intermittent engine stuttering.

[saffiewoo]

(Oct 09 update please read my last post)

I have a 1.9dg engine .

The problem is intermittent sometimes it will stutter as if there is fuel starvation and sometimes when this happens it will not tick over and cuts out and other times it will tick over and not cut out.
On some occasions when the stuttering happens i can not pull away from a stand still without it conking out as if it does not have enough get up and go.

At first i thought it was fuel starvation i checked the fuel line from the tank to the fuel pump all seemed well and clear.Although the fuel filter only seems to get half full?
So next it checked the fuel pump as it appeared to be the original one and on testing it appeared to be only working every now and then .
So i fitted a new fuel pump took it for a run, great cracked it it pulled well and went through the gears great.
Then it started stuttering again.

Like i said it does not do it all the time its just getting unnerving now pulling out of junctions as is it going to keep going or die on me in traffic.

Can anyone give me some pointers please.

Fuel filter only getting half full is normal, the air in the top half has nowhere to go so it gets trapped there!
Could be water contamination in the fuel tank, quite common as the filler neck can perish and let in water.
Renew rotor arm in distributor and all HT leads if these havn't been done recently.
Could also be a coil problem. Can break down and give these symptoms but usually only under load.
Your pushrod that operates the fuel pump may also be worn and not operating the pump properly.

I'll say HT leads . Don't buy cheap one I know everyone always says it about parts on here but I had a bad experience with some reciently

Changed the coil ,HT leads and pushed the boat out on a new rotor arm.
Just been for a run and all seems well .
Must say never had coil and HT problems before hence why i thought fuel.
So thanks for the help and fingers crossed its cracked it.

Cheers.

Hope you bought quality leads, did you replace the distributer cap and rotor arm ?

I have had 2 lots of similar problems, first one was the dizzy cap wasn't able to sit right as it was a cheap bit of tat from halfrauds, went to another motor factors and that has been fine, second lot of trouble was a split vacuum hose, sometimes it was ok sometimes it leaked.

1.9 dg engine pierberg carb.

Hello been a while since,
i changed the leads,dizzy cap,rota arm,ignition coil and a new fuel pump, fuel filter and up to today it had been alright ish .
It has been a bit hesitent sometimes but it came to a not so amusing head on a major junction this morning.

It just died as i pulled away then picked up and then seemed fine until i had to stop at traffic lights when i dipped the clutch it cut out and would not idle/tickover unless i booted the throttle so as nearly reving the daylights out of it for it to again cut out as i tried to pull away. Then as i pulled in the drive best place to do it really i suppose there was nothing at all despite how much i used the throttle and after a bit of faffing and being told not to swear by my son who was with me i managed to get it of the road and it conked out again.

Im at a loss as to the problem as you will see by the previous threads.

Anyone got any ideas ?

Cheers for any help or pointers you can give.

ignition amplifier or vacuum advance bit on the side of the dizzy


if its back firing change the ignition amp

if its just runinng rough, chances are the diaphram has split on the vacuum adavnce

both available from just kampers, brickwerks, GSF


phone round for prices

evening

exactly (and I mean exactly) the same thing happened to me earlier on this week. Pulling up to the lights with no problem, then all of a suden she starts stuttering and cuts out. I started her up again and had to really whelly the accelerator to stop her cutting out again. Not good!

Anyway, i limped around the junction and managed to get back on the road to get home - and the problem disappered.

These vans are getting on a bit now and so need loads of TLC - luckily we've got this great site to help out. So once i've re-fitted the interior she's booked into the van doctor.

ta for now

have you checked the fuel neck rubber behind the filler cap?

these get old then perish allowing water into your tank which then gets sucked up to the carb and plays havoc.

what condition is the fuel filter in?? is it clean?? and sign of crud there??

BTW do you have a filter by the tank too??

[saffiewoo]

Rincewind thanks for the pointer took the vacuum advance off and its fine after testing it .
JasonK fuel system is fine first thing i thought of other than a problem with the carb which has not been looked at yet.

After putting the vacuum advance back on the dizzy went to start it it fired up and then cut out straight away.
Then when i went to start it again it would not even turn over just a click in the dash ,battery is fine its done this a couple of times but then its ok.

Dont you just love em?

Anyway still looking for pointers on the original fault.

Cheers for any help Gary.
