Gday guys, i'm in need of some advise.
I have an 03 wk ls1 stato. (Always a commodore man though, and soon to be again)
Every time i take her up and over 5000rpm all the electrics shut down, (radio turns off, aerial goes down, traction control kicks in, then theres nothing at all, almost instantly) and she just dies in the arse! till the rpms drop back down.
Then everything comes back to life and she's good to go again.
She doesnt stall out though, the engine stays on, its an automatic..
She runs smooth all the time, unless i take her up to high rpms.
I had a mechanic look at her and he checked all the earths. And also put a new earth lead from the battery to the block.
He gave up and has no idea what is causing my dramas.
Just wondering if any of you guys have had any similar issues?
Cheers
