secondary air injection.
I have been looking for leaks in everything, I did a pressure test and only found a very small one.
I read a post from kodeTT that it could be the relay and would like to check that but I have no idea where it is.
This is on a 225, the previous owner had the DV replaced about a year ago, its totally stock, should I be looking at this as well?
the car seems to be running great, I dont have a boost guage but it feels like its making full power.
I plan on ordering a hose techniques kit also to replace everything.

thanks
