Air fuel ratio, have virbation

[clanbuster]

My car have idling problem every morning.
My gearbox is auto.
The car always have high vibration when the car stop on "D".
But this problem go away when is afternoon or at night.
There is no problem for this until i had install turbo.

Could it be:

1) at idle speed, i believe that turbo is turning and i guess there is extra air entering into engine cause too learn?
2) at idle speed, i believe that the inlet pipe is too long and cause less air, so insufficient air into engine cause vibration?
3) yr comment

I don't have Air fuel ratio gauge. So i not sure what happen to my engine.

since u add bolt on
did you remap the ecu???

 

[studsme]

did you do tunning? how is your air/fuel ratio? on a cold start turbo car tend to have higher a/f ratio to run the engine and rev higher. try to let it warm up to normal driving temp then move off

my 2 cent
correct me if i am wrong
