Misinformation
P1336 - general misfire
P1337 - misfire on cylinder 1
P1338 - misfire on cylinder 2
P1339 - misfire on cylinder 3
P1340 - misfire on cylinder 4
These codes are manufacturer specific, so mean different things on different cars
They are also engine management system specific, so...
Heard this quite a few times now.
Don’t be so quick to condemn your timing chain because it’s ‘a well known fault’.
There are other things, e.g. fuel pumps.
I would see if other codes emerge in the next couple of weeks. If you have a logging code reader/dongle you can capture data while...
That sounds exactly like fuel delivery issues, not timing chain.
It happens under load: more fuel required, but it couldn’t be delivered, due to low pressure.
Mpg readings showed blank: no detectable fuel flow, due to low fuel pressure (I’d forgotten, mine did this too when my pump failed)...
Not sure your code has ever been associated with a timing chain issue. They’re normally more like a reported phasing issue or similar and applies to the whole bank, not just a single cylinder.
In my mind, it sounds more like ignition (coil or carbon build up) or high pressure fuel pump.
I know...
Mick - good to here from you!
There is a story, but I won’t bore here.
Being a Boy Scout in a previous life, I like to be prepared, so it was a question that came into my head, the answer for which might save me some grief and swearing one day.
Cheers.
For more info., it’s a R version and I can’t quite see the best access to undo the clip that secures the air hose to what I guess is the inlet manifold. It’s a bit buried between the bulkhead and engine, so I wondered what the best way to reach the clip fixing was?
Any one know the best route to access the clip that secures the air hose from the air box to the intercooler - the one that runs over the top of the engine at the left hand side (viewed from front)?
Is it from underneath or through the wheel arch?
The Peugeot wing mirror caps went out of stock many moons ago. None to be found nowadays (in practice).
Wrap or stick on cap are the only realistic options now.
Depends what the issue is. It may be as simple as a disconnected sensor.
Is the engine management light on?
Are there any warning messages from the dash?
You really need a logging OBD tool.
Clear the codes, go for a drive while logging the data, Hope the issue reoccurs, analyse the logged data.
Fuel rail pressure is logged, so you can graph it.
This is how I found mine.
If you’ve seen P0087, that’s usually conclusive the pump has an issue...
