1998 Peugeot Boxer 2L petrol, engine sputter

Post by Jmaracas »

Hi all, my 1998 Peugeot Boxer 2L petrol, engine started to sputter and choke under acceleration during my last trip, once it's up to speed it goes away. I noticed water collection on the block between plug 2 and 3, extracted plug 2 found it to be filthy with water in external plug chamber, inside seemed fine. I changed the plugs, leads and coil but it still happens, engine idles fine, I rev and sometimes it revs fine, others it sputters and hunts.

There is no OBD2 port inside so not sure how to diagnose

Any help much appreciated
. thanks all

Cant imagine there are a lot of 2L petrol Boxers around, sounds like quite a rare one.
Have you rechecked the HT leads are not getting wet again?
This year of Boxer will Likley need a 2 pin connector for diagnostics but you will be very limited on what info you can get out of it.
Theres a good chance that you wont even get a fault code out of it unless the engine management light is on.
Have you done any other basic checks like replacing the fuel filter if its not been done for a while?

Thanks for the reply, It's a motorhome, I will have a look at the fuel filter but doubt that would cause the issue (unless it's restricting fuel flow).

Changed leads plugs and coil yesterday so no moisture on them.

Thats the idea, it may be partially blocked still allowing some fuel through but not enough when its under load?
Im not sure what type of fuel filter is on this a I cant remember ever seeing this engine in a Boxer but its likely the only way to 'check' it will be to cut it open.

I would also put a failing fuel pump on your list of components that could cause these symptoms.

It's an in-line fuel filter, I had to get under the van to locate it near the fuel tank attached to the underbody. Hopefully that does the job, if not I'll have to look at replacing the fuel pump.

Changed filter, has not solved the problem, any clue on fuel pump? Do I have to drop tank to access?

Do I have to drop the tank to get to the pump? Or is there a hatch

On diesel models there is an access panel in the cab floor, cant imagine the petrol model would be different.
