I have a 2003 turbo s and when I drive a lot of the time the boost gauge says I'm getting boost but it will stall for like 5-10 seconds then it goes does anyone have any idea what this is. Any help is appreciated!
Have you scanned the car for trouble codes? Please post any and all trouble codes. I had a similar problem on my turbo s; it turned out to be the diverter valve was worn and sticking, plus the n75 valve was also not working as it should.
These threads describe my problem and the solutions that I found for the hesitation issue:
I agree with billymade it could be one of those or both needing attention. check your regulator valve(hockey pok) too sometimes that sticks intermittently. I would remove all those valves, clean, test and also clean the throttle valve.
