On my ED 4.0ltr there is a sticker under the bonnet that says idle should be at about 600 or so rpm.(its an auto) Problem is that the tacho reads it at idle to be about 300-400 rpm. And yes i have read it correctly, checked numerous times:). The car doesn't idle rough or want to stall, infact it seems to be running perfectly normal. I only noticed this since i put an s-pac dash in about 2 months ago, but its not running any different from b4 the dash went in. So is the tacho reading slightly wrong or do i need to up the idle? And how do you up the idle? Thanks in advance
