just had a call from lennie (who has got my car for a few days whilst i'm im in dublin) and aparently after he picked the car up its started to miss quite badly. will die when idling etc. sounds to me like ts either running on 5 or 4 (remember, v6 )

now if it turns out its only running on 4 and the 2 not firing ll happen to be on the same coil (coilpack x3 wasted spark) wht "bits" will need to be looked at? wht bit of wiring, connectors etc.?

obviously the edis unit itself nd the coilpack itself, but my car is notorious for bad wiring, so that would be 1st place to look...

anyone know how the edis "talks" to the coil and could use that info to work out how to trce a wiring fault if its not firing 1 of the coils?

OR is it case of it will NEVER fre only 2/3 of the coils even if it get a bad signal, therefore the coilpack must be knackered? (or a plug/lead is fooked)


OR my engine just lost a piston doubtfull tho

 

sorry for spelling, using GF's laptop and he keyboard is shite

 

try this web site jimbo ...

Saves me explaining stuff

 

si, THANKS

could you just answer the last Q for me tho... is it possible for a nonfaulty coilpack to just fire 4/6 cyls? saves me working it out for myself

 

Could be leads, either of the paired plugs, a single coil within the pack, wiring, or edis.

Nothing else !!

UNLESS the crank sensor alignment or sensor itself is wrong !!


Sorry, impossible to say for sure I am affraid without being there

 

so the coilpack itself doesnt have some sort of fault tolernce thing that means tll fire a coil even if its not told to?

 

just to let peeps know, it seems to pull fine after a certain rpm... which leads me to belive plugs and leads!

 

Jim, the coil pack is JUST 3 coils on your car nothing else.

I would swap leads and plugs around to see if the fault moves around.
Otherwise change the plugs and/or leads.

Without proper diagnostics, the only way is to change things till its fixed !


EDIS will always fire a coil irespective what the ecu is doing.
For example, If you disconnect the ecu and crank the engine, you will still get sparks !!

 

si, the point i was getting at is will the coilpack do out withut the edis connection i now realise... of course it wont... lol

lennie check this
ie if the coil doesnt fire, the rev counter doesn get the pulse...

so if it shows <6250 rpm on the limiter (feel free to rev the tits off it ) then its not tryin to spark
