Just looking for some advice here.
Car is a 2005 Vauxhall Corsa 1.2 with 67,000 miles on the clock, factory fit
LPG system. A few weeks ago when I started it on a cold morning it was not
running well and the "Exhaust Emission" warning light flashed a few times
and then stayed on, I had managed to cover about 1/4 mile, thought it might
be dual fuelling so switched over to petrol. Restarted engine and the same
again, limping back home, car did not have enough power to pull up a small
incline. Managed to switch it over to LPG where it picked up and ran fine.
Travelled to work switching between petrol and LPG and no problems at all.
The problem raised its head again on Tuesday after being parked all day, it
was very cold, around freezing, again after re-starting engine and all fine.
Car has been into the garage who reported back 7 error codes, mainly to do
with ignition/misfires varying across all the cylinders and one of the O2
sensors. They are blaming the LPG system but I thought that because it is
running fine on LPG and the problem only shows when on petrol it must be
something else. Anyone got any ideas?
Thanks

With my my very short experience of owning a corsa LPG so far I have
decided it is best to always start on petrol, and only swap to gas
when it is warmed up a bit. If I switch to LPG too early as soon as I
change gear the engine stutters and switches over to petrol itself
(flashing LPG light) - because of this I wait until I am on the open
road in 5th gear before changing to LPG.

When I read what you wrote it looks as though you start it on LPG even
on a cold day. Do you know if the problem still occurs if you start
on petrol and only switch to gas when the engine is warm?
