Good afternoon ladies and gentlemen,

Car - JDM AE86

Motor - 7AGE, Stock loom, all sensors hooked up etc.

Problem - Car keeps blowing the 'EFI Main' Fuse in the engine bay fuse box. The car can sit and be revved at idle, but as soon as it's put under load being driven, the fuse dies within seconds.

Funnily enough it hasnt done it for a week or so (being intermittent), but i need to get to the bottom of it (for obvious reasons).

Possible problems? I have read on some toyota forums that the wiring to the O2 sensor can cause dramas like this, but I have looked over mine and it seems fine, Any leads (LOL pun) are much appreciated!

Cheers DC,
Robo
