Trying to hold on :(

Oh yes, to set the record straight......

If you have a faulty coil-pack, theoretically at least it's failed for a reason (they shouldn't spontaneously fail) so now is the time to systematically examine the rest of the ignition system carefully. Multi-plugs, leads, spark-plugs, even engine earth straps etc. These bipolar DIS systems are very 'fussy', and what might seem inconsequential to an older style ignition system may really upset a system like this.

They have been known to crack and earth to the body.
 
Sorry, I misread it earlier, it is the three bolt pack that you need.

Is it definitely ignition related? From 9.5 years of ownership, the one recurring issue was that very few people know anything about these cars and bull**** their way through repairing them, at the owners expense.

haha, yeah im beginning to find that! :( The only signs are, terrible on idle (almost stalling territory), jerking in low revs in each gear (its an auto so i cant just switch down easy) and engine like flicking like theres no tomorrow. Which for her there very might not be if she dont start behaving herself!

Correct, I've had a couple fail over the years and had cracked underneath. Like anything else electrical, it can fail at any time and without any outside influence.
 
Secondaries being open can cause bad idling and makes the car jerky when pulling off but the car is fine at higher revs, but I don't think the engine management light would flicker. The linkage on my secondaries popped off once and made the car jerky on idle, as well as when pulling off. Worth a look, if nothing else, to rule it out.

 
Hi Adam, I have a C2 & had the same problem as you have, after I went through a large puddle I did not see, the engine light was flashing, it turned out to be plug number one needed changing & the leads were cleaned. fault codes cleared & now runs sweet as a nut,

No idea mate. They cost them £13 each so dunno if that makes them any good........



For the cougar 2 shaggy? That seems to be my problem :(
Yes its from a 2001 c2 mate 3 bolt. And as for your mechanic £13 quid a plug he's taken the p***

Listen I'm doing a trunk every night this week to Warrington so I can take the coil pack with me if you can get over for it.
 
The big cat is very choosy about what plugs it likes. As for coil packs, I am sure there is an intellectual reason they go at a specific juncture (benners?) or perhaps like every other moving car part they wear out at random rates.

Don't have a degree in this subject or indeed brain surgery like others, but as the resident car spaz I have learned things can just break

I've just been round the corner to do an urgent errand and the engine light's flashing like crazy, Im not sure she'd make it to Warrington :(

Funnily enough on the drive back from Sheffield it was when I went through a big puddle when it started to flash! If it is a plug that needs changing, I'm gonna kill the garage as they said they changed them all (even apparently the "one thats really hard to get to and most garages don't bother to change because of that")
 
A spark plug socket, a 10", 3/8" extension and about 6 minutes is all it took me to change the back 3 plugs in my car. The one closest the IAC valve seems to be the tightest to get at but not a problem at all.

I'm using Denso plugs at about £6 each with no problems at all.

Anyone got a baseball bat for a rather RUBBISH garage :)
 
I would have asked to see all of the old plugs

Trouble is they just sling them in the bin. Same goes for filters, gaskets...

When you take it in, just say, "I'm pretty sure I can feel a misfire and I think it's [random cylinder on the back bank]." Doesn't matter what cylinder you say. "Can you please keep them all so I can check their condition?"

Of course if you're having to resort to this, get a better garage.
 
What he is getting at is, Ngk are ***** in a cougar and can often lead to misfires.

Motor craft have a much better record.
They really that bad?
I'm using some NGK Laser Iridium plugs (best ones I could get) in the V6 now, they weren't cheap (£58 for the set) and they seem to be running spot on. Is this something I need to watch out for with 'em?

You may have got a rare good set. But for those looking to buy I don't really know how to justify £58 for temperamental plugs as opposed to £30 for far more reliable ones
 
NGK are generally a first class product - no doubt. For some reason they just really don't seem to last long in the Ford V6. I've no idea why. I've used them faultlessly in many other cars and still consider them to be a good manufacturer. I have first hand experience of them breaking down shortly after installation in a Cougar too though getting misfires and evidence of blow-by.

Ironically, NGK make the OE plugs for the Jaguarified version of the same engine. They work perfectly well in that application and they're what are still working in my S-Type which has just ticked over 70k and is now due a service to replace the plugs, and they're what I replaced the old NGKs in my X-Type with 9k ago when it rolled over 70k.

I have absolutely no idea why so many fail in the Ford version of the Ford V6.
