Hi all
For some reason my car is not running right. It is really hesitant. I have had a new airflow meter, knock sensor, coil pack, leads and plugs, turbo inlet pipe, and it was still the same then it started over boosting sometimes going over to 20psi so today I have bought a turbo smart boost controler and the boost is running around 10-12 psi but the hesitation is still there like it have no power. Anyone have any ideas.
Many thanks

 

What kind of hesitation is it? And what car? Are the plugs gapped properly?

 

plug check ! could well be one down, coil pack ,?or possible maf problem,? cam sensor.? partial feed of fuel poss block injector which would prob throw a code. hope u get it sorted mate.

 

It's an impreza turbo2000 if I put my foot down its sort of hesitating but Ido take my foot off the throttle let put it straight back down its fine.
