Title: Re: Idle problem Post by: prj on May 28, 2012, 07:51:59 AM 0.9 temin is way too much for these injectors. That's why you are having this problem right now.
When you set temin correctly your problem will go away. Title: Re: Idle problem Post by: professor on May 28, 2012, 10:46:25 AM Also put same values on temin & teminva.
