Default Drivability Issue - In Vacuum issue

Hi Everyone,

I am having a small drivability issue. At times, my Miata runs a little rough where the car wants to accelerate/decelerate slightly and rapidly. I notice that the turbo gauge indicates that the in vacuum is bouncing up and down a bit. If I put my foot on the clutch and blip the throttle, it sometimes takes care of it for a little while. It drives me nuts. Other than that, the car is running great.

Set up:

01 Miata w/ FMII turbo kit with Hydra

I'm not sure what other information would be helpful.

Thank you for your help.

Greg Savoie

I am sorry for what I am sure are stupid questions. How long a log should I take? What would be considered ideal AFR?
