I never ran into this problem with my procede, I hear that a possible solution would be replacing the turbo solenoid? Any idea where I can find one? I normally get an "engine malfunction" light if I'm at high RPMs going in 3rd gear
Doesn;t have to be a boost leak, could be boost control.
from what you're describing, it could be your boost solenoids. Before changing these, I would double check all vac lines. canisters to engine, canisters to boost solenoid, boost solenoids to wastegates...
if all looks good then change your solenoids.
