While driving the revs blip down to zero then back to normal. Engine cuts out while driving AND idling, particularly when putting into neutral. Don't think it's ignition leads as they are only 3 months old. Any ideas?

Hi blade
Sorry to hear this and not being the local mechanical guru here , but maybe it could be the dizzy problem that Mazda 6,s suffer from, others will point you in the right direction, no doubt

Yep

Deff sounds like the dizzy problem, do a search on the board m8 and you'll find your cure :).

Hi mate..

Exactly the same thing happened to me a while ago. It vuts out, and get progressivly worse very quickly,.. you will find you wont be able to start it at all within a day or two.. so better to get it checked sooner.. youj can pick up a new dizzy from a scrap yard for as little as £50, so it shouldnt sting too much

Is your problem fixed yet?

If not - I had the same problem a while ago it turned out to be the Distributor, but after changing it, it lasted for two days and again the disty said bye, bye.

It turned out to be the crank angle sensor, which you will find at the front crank pulley - it went for a ball of $&*% and send the wrong pulse to the disty which caused my new disty to pop again, so you might want to check out the sensor as well.

If you got access to a manual you should find the values of what the pulses shoud be coming from the sensor. Sorry I had documentation on the values but could not find it right now.

I will have a look tonight and post it as soon as I find it.

Thanks Telstar ... no its not fixed yet, its going in to the workshop today (thursday). I have a Haynes manual and it appears there are two sensors, it calls hem the Crankshaft Position (CKP) sensor and the Camshaft Position Sensor (CMP. The latter one sets a diagnostic code, if it fails so I'll have a look at that first - although THAT one means a replacement distributor (mazda price 400 quid, probe price 590 quid ... aaaaaaarrrgghhh) and I dont know if the CKP sensor on mine is in the distributor or on the engine or both, as it seems to indicate in the Haynes manual.

we'll see sometime today.

(bring back my old Audi ...... :-( )

Both sensors are inside the dizzy, and when buying the ignitor module (from fraud) both sensors are fixed to the module.

You don't need a full dizzy (mazda dealers only sell the full monty)

Get the parts from Ford - you'll need both:

Coil assembly:
Part Number F3974598
Approximate cost £53.00 + VAT

Stator assembly:
Part number F3974599
Approximate cost £39.00 + VAT

hmmm, thanks for the info and advice guys - as you might imagine, I'm trying not to spend unnecessarily on this, so being patient, my friendly mechanic, and an auto electrician, checked out the (integrated! thats new to me) coil, distributor (which looks brand new) sensors and diagnostics and the wiring in between the lot and no faults found and we couldnt reproduce the problem.

SO at the moment, we're avoiding long journeys hoping the prob comes back so I can drive right round to the garage when it does.

wonders .... could it be the immobiliser - I know its daft, but when it starts to misbehave, the 'blip' in the revs is about at the same frequency that the immobiiser light flashes. No forget it I'm going mad.

Good news is once it's fitted, it wont go again.
The main difference is a much larger transistor... maybe this could be replaced on the old model..
Shame about Fraud putting the price up.

cut out

hi Blade ,have you sorted this out yet ?
Mine does the same but re-starts after a short time, but not getting any better!
Watch out as the cut out puts unburnt fuel down the pipe, causeing the cat to melt!!
This may give you high co2 reading on your next mot test.
at www.probedistributers.co.uk they sell a new dizzy £200 + vat
or a repair kit at £150 + vat inc cap and arm plus the parts to stop the cut out. the tel number is 07973 315349.
Hope this helps.
If you use them let me know or Iam off to Fords.
