Hi all

I have a Peugeot boxer 1998 petrol Ravenna.  When out the other day
the van the other day it stated to lose power initially in 4th gear and then
even in the lower gears.  When you turn the ignition off and back on again
it starts OK andthen runs for awhile before doing the same again.

The mechanic has drained the fuel tank and cleaned out the system,
there may have been some water in there.  The fuel filter has also been
Changed but the problem still continues.  We have tested the exhaust and that
is fine.

Has anyone had a similar problem who can provide any ideas

Thanks

Carl

Filler cap breather blocked?

EDIT: Easy to check, just take the filler cap off when the engine starts labouring, if there's suction there that could be the problem.

Not exactly the same symptoms, but mine was down on power & had a lumpy tickover.
Bought some of this:

I actually removed the injectors and left them soaking in it overnight then refitted them and put the stuff in the tank like you're supposed to.
Cured mine up!

Filler caps don't have breathers nowadays, the breather is separate

There's supposed to be a slight vacuum in the tank,its a safety thing. Never noticed the slight hiss when you take the cap off to fill up?

No Frank, we don't have any petrol vehicles any more, and I don't know when things changed to have a tank vacuum as normal, so I defer to your superior knowledge, t'was only an easy to check suggestion as the vehicle is '98 vintage.

As an aside, how do you maintain a slight vacuum in the tank when petrol has such a high vapour pressure, especially in warmer weather?

Well it was before my 1995 van was made smile! Not sure about the exact science, but the tank 'breathes' into a canister which opens at the 'optimum time' into the intake system when the fumes are burnt by the engine. The ECU decides when the optimum time is.

Have you checked that your brakes aren't binding? i.e. sticking caliper(s) or handbrake not releasing fully.

Thank you for the response.  I will speak to the mechanic about your suggestions and see what he says.  Really annoying as don't have the confidence to go too far in the van.

I am sure we will get it sorted

Thanks
