Occasionally while driving along (usually a within a minute of starting when warm) the emmisions light flashes and the car loses power, it feels like 2 cylinders are not firing or sparking.

If I switch off then on it is fine - all the way to work.

Switching fuels makes no difference either.

So what do you think I should check?

The ecu for error codes would be good place to start.

If the emissions light is flashing....that to me suggests your chucking unburnt fuel straight down the exhaust.....so possibly an ignition problem.....coil pack maybe?  :-/

[Martin_1962]

However restarting the car solves the flashing. Very odd - I'll check the plugs one evening and see if anything is obvious

[Taxi_Driver]

Flashing emissions light means extremely way off emissions.....turning the ignition off and back on seems to be reseting whatever has gone iffy.

Can you get the codes read? It should at least be recording missfires being detected.....so will tell you which cylinder/s its occuring on.

I'll ask the TreVoR mechanic with the code reader to have a look sometime this week

I have had the same problem on my 2002 2.2 DTI, it has come on twice in the past 2 weeks, as soon as I turn the motor of and back on it goes.
The car is running as sweet as a nut??? does not make sense.

Yours is a TD....Martins and mine is lpg converted.....it can be normal for the emissions light to come on running on lpg...a flashing emissions light could be serious tho....never had that on mine....TD's dont know about im afraid...diff prob i suspect

[Craig_R]

Yep I get the Emmisions Light on now and again from running on LPG checked the codes and its just 0130 lambda sensor restart and its gone but its never flashed.

Hmmm, wonder if yet another cpp unit has failed....

[Martin_1962]

The plug looked horrible so it now has a nice new set of NGKs in bank 1-3-5

I will do 2-4-6 tomorrow.

I think it was failing due to knackered plugs

Hope so. Looks like 1-3-5 cpp unit isn't a TC item (though 2-4-6 is)...

So do I, 1-3-5 is £65 on Ebay.

I will keep a look out and see what happens, anyway NGK plugs are not that cheap - I wanted twin electrode rather than 4 as it is supposed to be better with LPG.

I will photo the old ones tomorrow and stick them in this thread
