Hi Guys, i am replying on behalf of Muckey,
a few weeks ago injector 4 went, subaru replaced that, then next the car would go fine and would just lose power, when this happens the car boosts at 0.4 Bar ... someone diagnosed it as a vacuum hose but all have been checked. he cleaned around the actuator as there was alot of dirt and this seemed to cure the issue temporarily. its happening again now, he is using a HKS S SQV atmospheric dv
Thanks
John
