Hi
Looking for help with a friends 2007 Touring.
Its totally stock.
Map 20367
He has had it about 7 months.
22000 miles on clock.
History unknown.
This issue started a month ago, occasionally it would cut out coming to a junction.
Then it started missing and kicking at low rpm cruising, occasional backfire and a sharp click from under the tank.
Under acceleration its all fine, pulls like a train.
TuneECU - no error codes.
I suspected an ignition problem, and bought new iridium plugs, air filter, 2 aftermarket coils.
Stripped it down, found No2 plug lead open circuit, and spark track marks on the lead.
Fitted new coil + leads + plug caps.
The occasional backfire and crack noises have gone, but the missing or kicking is still there.
Fitted the other 2 coils on their bracket from my 2013 Roadster.
Still the same, so there was a problem with front coil, now sorted, other coils shown to be fine.
So the big question, what's wrong with it?
Pictures show: -
One of the plugs, they all looked the same
Dissected plug cap, showing burnt 5K resistor
