I was driving from work the other day and while cruising i hear the car starting to sound like a WRX.
Just for a half a km or so then all is fine she ran great again.
Got home and switched off.
Next morning went to shops and back about 3 km and as i pull in at home there again in 3 cylinders ever since.
What i did so far is as follows:
Checked for spark. No 4 got no spark.
Changed spark plugs.
Changed coil packs and still no 4 no spark.
Did check my CAS Fuel injectors and fuel press and a good compression test and all good.
Not sure if it can be the ignitor or a wire break in the loom somewhere ?
Need some input as this is baffling me.

Thanks In advance guys.
