Hery everyone, I'm new to this board but i have an 89 s10 2.5l. This has been my project truck...I got it for free and it didn't run when i got it...lol. But now it is running great and i found a nice new bed and stuff. Anyhow...my service engine light comes on when i'm in traffic idling for a long time...and it comes up with a code 35. I read something about it meaning it's idling over 150 rpm out of the acceptible range or something. I'm just wondering how i adjust the idle or if there is some type of control. Thanks for any replies!
