Car stalls after rev...
 

Hi guys,

I have a supercharged mp62 2000 miata with a greddy emanage and a wideband o2 sensor. I recently started to have a problem where, when the car is cold, for the first 10 minutes of running, the car will stall if I rev it for more than 3000rpm. In general, I can rev it after idling at 1K rpm and let off the gas and it will dip below 1K and sometimes stall or barely catch.

I don't know if it is a coincidence, but this started happening after I cleaned the air filter. I have checked all the clamps and everything seems to be tight, so I am not sure why this would affect it. I just bought the car so I am new to the forced induction thing.

If you have any ideas, I would love to hear them. Also, is there a specific way you are supposed to adjust the idle other than just turning the screw?

I am also throwing two codes, one is for unexpected idle rpm and the other is a lean condition in bank 1.

Thanks!

Cold Air
Supercharged
Still got MAF?

You sir, have the idle dip problem of all supercharger mods.

Solution:
Dual throttle body mod or
Ditch the MAF

Yup, still have the MAF...

Since I'm a noob, I haven't heard of the Dual throttle body. I guess I will look it up.

Anyone have a quick link to info on that?

Thanks BarbyCar....
