Hi guys,

just came back overseas and I had disconnected the battery before I left. Now after coming back it has been disconnected for a month and when it came to reinstalling the battery and starting her up she now runs like a slug.

Basically it was in peak performance when I left, and now it wont even redline when I cane it. I want to know what it is and if any of you guys have any ideas to why. It was garaged for a month without a battery, so it wouldnt drain itself.

Cheers.

One of the reason its doing this is because you have reset the ECU, the battery only has to be disconected for 30 mintues and it will reset. so the only thing you can do is just let itself relearn everything, which will take roughly 200-500kms of driving.

I believe this may be what is wrong.

does it stilll have the old petrol in it??
if so drain it out and put some fresh PULP in there

yeh i had Ultimate in there when i left.

I'm going to fill it up on ultimate and change oil, filter, plugs and leads this week.

It just lost so much power it aint funny. Cant even kick down when over taking, its so pathetic.
