feels like kangaroo petrol,

[camaroneil]

hi,
my wifes puma felt like it had kangaroo petrol at quarter of a tank,
then, it started at half a tank,
now it happens at full tank,
the little red light to the right of the clock comes on for about a second and the temp gauge starts to rise and then drops back to where it was,
there is one code pending, it's P0321
i'm presuming a fuel starvation could cause this code as the engine could be momentarily dying and then the signal would be out of range,
any ideas????

Have you checked the fuel filter?

 

[camaroneil]

not yet,
just thought that would affect it all the time and not just when it was over half full,
i know it's happening all the time now, but it wasn't at the start,

Sounds like symptoms of faulty Lambda sensor.

 

[camaroneil]

right,
new fuel filter, still the same,
gonna start disconnecting stuff and see if it makes any difference, hopefully it will go into limp home mode and drive ok,

 

[camaroneil]

well,
disconnected maf, no difference,
disconnected lambdas, no difference,
disconnected sensor beside oil filler, (presume it's a cam sensor) drove like a dream,
theres 2 sensors on the cam cover, are they both cam sensors????

 

[camaroneil]

anyone know what the sensor is that i disconnected as can't find one anywhere,

I think the "sensor" you are looking for is actually the variable cam timing solenoid.

 

[camaroneil]

vct solenoid, thats the fella,
drives great with it disconnected,
thanks

 

[camaroneil]

still can't find one,
can i just leave it disconnected????

 

[camaroneil]

forget all that rubbish i said about it running ok now,
it doesn't, it still runs like crap,

 

[camaroneil]

right,
just a quick update in case anyone else hits this problem,
took tank out and fuel pump filter was partially clogged,
it's looking like this could be the problem,
will confirm in a few days after i've blasted it round for a while,

keep us updated.

Sounded like a faulty lamda to me.

But if you've found the cure then thats great.

Cheers

well, turns out the fuel pump was on it's way out,
just fitted new pump and everything is fine,
