HELP - Bongo losing power

[backtap]

Planning to head away for weekend tomorrow but noticed on the way home this evening that my Bongo has lost power. It's 2wd auto. When attempting to accelerate I get a very slow response, revs build very slowly and it gradually moves faster. If I try this on a gradual incline then it's a lot slower, in fact noticeably loosing speed up hill despite more gas.

It doesn't sound or feel like a slipping clutch (as I would expect on a manual - I'm not familiar with how this would sound feel on an auto). The engine revs fine in neutral. Any ideas? I've not got the hold on either - I can hear/feel the engine changing down when I try to accelerate but it seams to change up a lot quicker than I'd expect with-out much extra speed.

Thanks in advance...

We've had stuff like this before. Have a Search, but I can recall something about a small pipe that attaches to the turbo unit. If it comes off then the car behaves like you describe. Air filter (or something stuck in hte air intake under the bonnet - its happened more than once) is another possibility. Banjo filter (search on banjo) getting blocked is another (have you been using veg oil or biodiesel, or running tank v low?) as is possibly main fuel filter of fuel tank breather (try running with fuel cap off to eliminate that one). Also, cant remember but Throttle Position sensor (search on TPS) can I think do something a bit like this if faulty.

Etc etc. Others with better memories and diagnostic skills will be along shortly to help no doubt.

Good luck and keep us posted as feedback is invaluable for the next unfortunate soul.

Yes I have been running it on veg but I've not done so since it became almost as expensive as derv. Changed fuel filter shortly before I stopped running it on veg. Purely derv for 4-5 months now so I wouldn't of thought it would be an issue.

Will search on the other terms -

thanks

Had exact same symptoms recently - cleaned banjo and fitted new fuel filter and it was OK again.

I'm searching through the stuff on Banjo filters (there is a lot) but no one actually says where it is or what is does - I'll keep reading but if anyone else could briefly explain I'd be grateful

Well done scanner. Two things to try out at the weekend then

[backtap]

Found it.......

the first thing i would do is change the fuel filter (you can get to it underneath at the drivers door)
the second would to clean the banjo filter on top of the fuel pump,,(under the drivers seat)
this might help ,if not then someone else may post with different info that might help.

If I don't get it sorted first thing tomorrow the bongo won't be coming out for the weekend!

Info's in the fact sheets in the members area, with photos etc.

Hi Backtap, the filter is like a tiny little thimble, please be careful on how you extract it from the channel! It seems quite fragile, as a quick test, just remove the filter (temporarily) then take the bongo for a quick blast up the road, if all is well, clean the filter, then replace, and happy hols!

Hi backtap,

I would not run the engine without the filter,you may have crap in your tank,or the fuel line.

Cheers Mal..

The banjo bolt seems to have 2 washers - when you remove it take care you dont lose one or both into the dark space under the engine! I did so I would appreciate info on where I can get another one if anyone knows.

So yours is the same as mine then..........................

I think they are just standard Red fibre washers which I think most good motor parts shops should sell - if you don't have one near you try Halfords.

Scanner - At the mo I am running with one wahser missing - are you too? If so have you found any difference in running, I wonder if the height of the entry hole in the bolt is critical?

Can't remember now but can't think that I've left it with a washer missing.

The entry hole is only a few mms across, the washer only 1mm or so thick and the inside of the banjo is quite a bit bigger than either, so I don't think that would matter as much as the possibility of leakage through the washerless joint.

Ronhud, have you removed the plastic undertray from below the engine to see if your washer is stuck in the oily grime in there?!

Not the most difficult job in the world, although it involves a bit of lying around - on the ground.

The tray is held up by a series of 10mm bolts around its perimeter, and a few in the 'middle'. Your 'ratchet' will also require an extension piece...
