so I have read a couple of posts here on idle issues and can't seems to find any solution.
2011 EVO GSR
Stage 1 Cobb with CHFF
So when coming to a stop ( rolling 10 mph in neutral ) rpms stay high around 1.4k and slowly will go down to 900 after I 100% stop ( sometimes will bound between 1.2k - 900 for 2 second ) . I have checked all lines no leaks that I can see or hear. I also have checked the line near the oil dip stick that is on tight. I had the same issue when I was stock but not as dramatic it would idle 1.1k then go back down.
Am I missing something that is on here ?
Or could it just be the flash tune ?
I have been driving with the flash tune for 2 days now.
I had a turbosmart BOV 50/50 installed on first day of flash tune and it would not close all the way even on tightest setting. So I took it off and put the stocker on.
Please help !!!!!
