Right ive read the coil pack thread in the maintenance section but.. and there's always a but.. My 'VERY' reliable AUM engined 1.8T popped a coil pack off the spark plug 2 days ago.. i scanned it and got missfire codes.. I pushed the coil pack back on and still the same.. so i put my old plugs back on that i know work.. still the same.. So i then tested each coil pack individually and cylinder 3 which was the one that popped the coil pack was a strong spark.. but cylinder 2 was a weak spark..
Also the car is idling fine but when driving up to 2k its a scooby and then for some reason 2k is fine ??

So my question is can coil pack 3 be fine and from popping 3.. 2 now be on its way dead ??
