Hi guys,
i have 1993 JZA80 supra and the master warning light turns on sometimes and ill have to either disconnect the battery or the EFI fuse.
i have tried doing the DIAGNOSTIC TROUBLE CODE CHECK but no codes were shown.
i have topped the break and engine oil.
but still comes up
any ideas what does that means ?
