Quick question... sudden cough from the Stilo, now cangarooing sounding like a fisherman's boat. Low power...

So, humping home, connect FES to show coil 4/D failure.

Is this left or right looking down the engine from the front? Left=timing belt. Right=battery side.

Number 4 is the right hand one looking from the front of the engine.

Numbering always starts from the front of the engine, which is where the timing belt is.

Thanks. Will test out my spare coil, sent to me by Phil (PNL) many years ago...

Changed coil. No cure...
???
Then connected FES again, to be told coil 1 was defective, and timing faults on all cylinders.
Swapped new coil from 4 to 1, an reinserted the "faulty" 4. And... perfetto!

Vrooooom!

Now, since a coil at FIAT cost 140 GBP (one) it will most likely be some UK shopping again.

Pulling up my old thread again.

I ordered a set of 4 coils from shop4parts, which were delivered just a few days after. I planned changing them all when I was installing my engineheater, but I haven't had time (for none) and today a new coil broke down - in a snowy storm. Not very strange that another coil failed, as they have all ignited identical times...

Strangely FES stated a injection fault at cylinder 3. So I changed coil 3, but now injection fault showed up at coil 2. Anyway, changed all 3 still Sagem coils to a complete set of 4 Champions. Car started perfectly right away.

Usually I don't change if I don't need, but the moral here is: If one coil breaks down, change them all four. And... the engine management don't necessarily understand the disease. What if I changed all injectors, and still got the fault? So, if you diagnose an injection fault - test with a coil change first. The symptoms were identical to the first coil failure, so why should it be the injector?
