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

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
-
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.

Just thought - worst case is unplug injector!

Hmmm, wonder if yet another cpp unit has failed....
-
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
-
Dunno if the 2.0/2.2/later2.5/3.0 twin electrodes would fit. £1.81 each on TC. As said, not sure if same size/heat as the quad type fitted to 2.6/3.2
-
Seems fine now - hopefully :-?

V Sorry to digress Why do VX do this? I had a pair of Track arms c/w track ends, one side was TC t'other wasn't, managed to gerimander some discount anyway... just weird.. Anybody know the reason?
Fingers X'd on the misfire..

Im sure they will.....fit the cheaper twin electrode types....i do :y
Just change em every 10k :y

Hope its cured it....when did you change your plugs last Martin?
-

I agree - I know some people like to get the 'full life' out of stuff, but I tend to change stuff more quickly at a time that suits me (ie summer!) to keep the car at its peak... ...in case of plugs, every time I have the plenum off....

In the blue 2.0 - only had this one 15000miles

TBH Martin Imber, may be worth changing them a bit more often, esp if you get a TC card...

I know!!!!
I forget that the car was not fully serviced when I had it but only cambelt kit fitted and had a recent oil change before I had it.
What do you think - plugs from 40,000 service or original!
I used to have a lot more time for car maintenance

You know as well as I do, only one way to ensure your car is properly serviced ;), so probably original if quad type.
I find that a little preventative work means I don't spend too long on the car - a stitch in time and all that ;)
-
I thought a plug change was specced at 80,000 miles :o for 2.6 / 3.2.
Changed mine after I bought it at 41k and they were still ok but past their best. Which reminds me. 4 of them are still in SWMBO's MX5 ::)

Only way to guarantee it is done properly would be to get my dad to do it, but he is not too well now.
