DIESEL MISFIRE

[ELZE]

Any ideas guys? Mine is a manual diesel model which runs like a dream when hot. However when I start up in the morning it seems to fire on 3 and has a splutter. This only lasts around 10 miunutes on idle but if I rev a little it goes away. I am thinking I may have an injector off or an iffy injector/ lift pump. Any diesel heads out there can offer some advice. I have put Redex in the tank to help clean the injectors but has made little difference. s far and I may have to do it again. I have 65000 miles on the clock.

Can the injectors be refurbed (new nozzles) or will it have to be renewed. Maybe I can get a used set off the forums?

Anyone else had this issue anytime previously?

Cheers

Mike

sounds more like glowplugs to me

Read my recent post on the attached link ( page 3 from the barrack obama stylee bit) before you start changing glow plugs, my lumpy misfiring startup turned out to be a poorly adjusted coldstart idle screw, basically if your cold idle is set above 950rpm the ecu will think that the van is being driven and switch the glowplugs off thus making the van misfire when cold, its a five minute job and you'll only need a 10mm spanner.

When van is stone cold Lift drivers seat, put key in ignition and turn on, you should see the cold start mechanism activate, turn ignition off undo retaining idle adjustment 10mm nut and with your fingers wind the idle adjustment screw out until there is only about 5mm sticking out of the left hand side.

With the seat still up let the glow plugs heat then start the van, as soon as it fires adjust the coldstart idle to between 800 and 900 rpm max, tighten 10mm locking bolt and feel really smug

Thanks, I will get to work and report back on the success or failure whichever it turns out to be.

Brorabongo is the only other member that I know who has a manual diesel. You could ask him if he has ever had the same problem with his and if so how he sorted it out. Probably noothing to do with the difference between a manual and an auto but then I am no expert.

I agree the gearing will make no diference, I was only stating the model because as sure as god made little apples if I hadn't someone would have asked 'what model is it mate' I have read these forums for a while now and am learing!

Well I have taken the advice from the suggestions made here and read all the other links and forums on the subject and there is a lot of good quality advice, Thanks! Problem is it's a bit too much to take in so I have put things in order and perspective and this will be my first line of attack....As she is running like a dream when hot and currently returning 28.3 mpg the first thing is to asssume that the glow plugs have not been changed since she was born. Its a relatively easy one to tackle at a modest price of around £40. If that fails then I will review the posts and follow the next logical step.

Pump timing should never be an issue as all the years I have had diesels I have never known a problem unless it has been removed and replaced by supposed diesel techie who has turned out to be a little iffy and cocked the job up!

You do get them as I know to my cost with my last TD5.

I am a 60's bloke who remembers when injectors could be removed and sent off for refurbishment and new nozzles fitted. They came back like brand new and I always had a spare set already done just incase. Seems like its a thing of the past but new injectors would cost a fortune?

That would be the last resort as there is lots to check and do before we get there.

£80 gets replacement nozzles:

Or £200 for set of new injectors:

Can't believe how cheap these injectors are. Last year I had to replace all on my TD5 and were £350 each! I am stunned.. Owning a Bongo just got better.

i have a manual tony.
sounds like glow plugs to me too.
fit good quality ngk glow plugs if it has short plugs, if they are are the long ones in there then you will have to modify the buzzbar or extend the plug tops.

Bear in mind that the Bongo uses old-school injectors rather than more modern common rail type with ECU driven actuators, so that helps to keep the price down .

Following on from the advice here, I purchased new glow plugs. tried to install them but fell at the first fence as I could not remove the front seat Removed the 2 bolts at the front and for some reason thought the seat just tipped back (hinged) could not find the other fixing Anyone want to give me another leg up! How does the seats come out? Doh!

I just rang a diesel bloke who wants £60 to do the job and the vehicle overnight? Would rather try and do it myself first before I consider that silly money

what motor is yours as on a regular bongo you just tip the seats back

[MountainGoat]

Two floor Bolts at the back of the seat to remove and an electrical connector to unplug. Then the whole seat can be lifted out provided that you have first removed the the center consol and unfastened the clips at the front of the seat.

If you have a side conversion, it is often easier to remove the seat altogether to get better access.

1) Slide seat back & remove front 2 bolts (can be very tight)
2) Slide seat forward & remove back 2 bolts
3) Remove bolt that holds the seat belt sliding mechanism
4) Lift seat out & then disconnect the plug mentioned previously
