Coughing?

[Guest EVL-R33]

ey, just finding a bit of a problem not sure what it is exaclty..

its pretty hard to explain and maybe im just getting used to my cars power,

but it seems not to be going as good as it was b4 not pulling as hard and at the higher rpm where more boost kicks in due to the solidnoid my car starts to like cough (hard to explain) it just cuts on and off but not all the time, some of my friends think its the Cold weather as it happens more in the early morning when ice is falling, another reason could be is i have a lil tiny crack in my ciooler piping where the clamp sits?

can any1 help?:confused:

Cold weather = more boost.

You could be hitting the boost cut.

The little tiny crack could do it - could open up under boost, releasing some of the already metered air.

Also, might be detonation with the ECU retarding the spark (unlikely).

I'd get the crack fixed.
