could be the wiring thats damaged
Yes, I'm also beginning to wonder if I have an intermittent circuit break
somewhere. That's why I asked the question about the crank sensor
code.
As said previously, the only code I ever get is 0335 with engine stopped,
and no codes with engine running. If this is a genuine fault, as 'TheBoy'
says, then it would point to the Crank Sensor, or it's wiring, intermittently
breaking down.
The car normally runs smooth as a nut. Idles beautifully at 750rpm. Plenty
of power when you need it (only 47,000 on the clock).
When the car attempts to stall on the overrun, usually approaching a roundabout
or throttle closed at speed on a downhill section of motorway, it gives a sound
that sounds phonetically as 'Psst-Choo', similar to that of a turbo car changing
gear. The car then carries on driving normally with the EML light on. If I stop
and restart, the EML light goes out.
The only other time it does anything, is if I'm sitting at traffic lights the engine
stops dead, just as if the ignition or fuel has switched off. Turn key off, switch on,
give the ECU 5 seconds to perform tests, and it starts normally with no EML
light on.
On the rare occasions that it actually stalls, usually slowing down approaching
and then re-accelerating to cross an empty roundabout, I pop the car into neutral,
cycle the ignition key off and on, start the car whilst still moving and it picks
up again smoothly again with no EML light.
Have rechecked breathers, still clear, checked for a vacuum on the small breather
pipe at idle, (nice strong suck that sticks my thumb to the pipe). All vac pipes connected
and no splits. No oil leaks. Plug wells clear.
Again, only Code is 0335 when engine stopped, no codes when running.
As it seemed to do the stalling thing after opening the throttle from idle, I wondered
if it had something to do with the fuel tank purge valve. This valve only cycles open
with the engine warm and the throttle position sensor indicating the throttle is away
from it's stop (ie engine under load). But I can't figure out why this would be, unless
it's richening the mixture too much, but the ECU would richen the mixture anyway
with an opening throttle.
So, all in all, it's got me a bit stumped. :(Sad
