Previous owner had the car setup for autocross, so the idle was set to 1500rpm when I got the car. I'm trying to get the idle down to around 1K for street driving, but anything under 1200 isn't stable. What I mean is, I can adjust it to 1K and it holds idle after the adjustment. But when I go for a drive and come to a stop it'll hold 1K for a couple seconds, then a whistling noise starts and revs start to slowly decline to the point that it would die if I don't blip the throttle.
I'm still getting acquainted with the DRLA 40's, so I wanted to see if someone familiar with them might know what's going on. Engine is a 2270. Idle jets on the DRLA are 75's. Is it possible I need to swap the idle jets out to a different size? |
