Cost way more than I was hoping, but previous servicing (including ones done by Holden) had done some dodgy work.
Was pretty nervous when he started calling with all the issues, but I went there and he showed me what was wrong.
New coil pack, spark plugs and then 100k service $1150 later....
Car is running like a dream though, which I suppose is the main thing.
Next service better be a breeze.
Cheers again
