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.

What are your AFRs doing then?

Please forgive my ignorance. What are AFRs?

air fuel ratio

what do they look like while you're having issues? you will need to take a log.

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