Coil Pack Problem Poll

[EZ2CME]

What is the go with the poll?

It has 20 votes but it is saying total 29 votes?

that's because even if you do a null vote it still counts it as a vote.

Ok I can say my coils have died at 95 000ks.

I have owned it since 87 000ks and don't know if it has had them replaced by the previous owner at any time while he was in ownership.

I have also noticed that there is different part numbers on 3 different sets I have.

Unless these numbers are a batch number.

This I thing maybe ford superceding them with better quality ones as there seems to be a problem with the BA series 1 coils from what I gather from talking to other owners at car events.

So has anyone else had any die, let us know what year and model your car is.

What symptoms does a faulty coil pertray? I have stronger valve springs and sometimes when I boot it and back off it sounds like it misses just like floating valve springs.

I havn't had a coil go yet but this might be it.

I found that they where causing car to miss and pop once boost climbed to over 10psi but only once the car started to accellerate.

Eg say you are at 2500 rpm in 4th gear WOT it and all is good, then once boost climbs and car starts to get moving say around 3500 it all goes crap, splutter pop.

Its like as if once there is to much air/fuel flow under boost they can't ignite it.

Mine started off with occassionally playing up to the point where everytime I WOT it , it would do it.

I had changed plugs, regapped them etc with no result, changed coil packs and yee ha all good now.

Coils can slowly wear out, and reduced spark strength can be a result.

On older cars with single coil ignition systems this could be easilly pin pointed as the one degraded coil would drasticaly effect the cars performance... cutting out ect.

But, with our cars, we have multi coil, or coil on plug as some like to say, and the results of a failing coil can be harder to pick.

If one coil is faulty, usually due to heat, it can intermitntly fail cuasing poor idle as one cylinder is no longer getting a strong spark.

Its a good idea to test the charging system, and battery's loaded amperage... a poor battery can dramatically effect spark/ performance as well.

Thanks Rapid on that info.

That is another thing I mentioned on the Coil poll.

The heat being a problem.

As the coils are at the top of the engine where all the heat goes and the fact that they have no ventalation I would feel that the heat in around the coil packs is very high, not good for coil packs or anything electrical.

Iam going to look into some sort of vent setup to get the coil temps down.

Even if it is just to perforate the cover it will get some temp away from the coil packs.

Does anyone know anything about these coils on ebay ?

I think I've got a crook coil but I figure for that price I might just replace the whole lot.

I actually think this is the reason why my car idles like poo in the last week.

Nizpro will find out for me tuesday

I contacted Splitfire to see if they made aftermarket coil packs for XR6T, they do hi po packs for other motors. But unfortunatly, they have nothing suitable.

I think I have developed an intermittent coil problem, it is very random though, doesn't happen very often, happened twice this morning, but not once tonight...
