acceleration. No check engine light. No vacuum leak/checked hoses. Only shop to work on it was at Subaru for the recall in which they replaced the fuel line underneath the intake manifold. This was over a year ago, and I don't beet on the car. So Now I get hesitation, mainly at higher speeds, surging is a better word. Just wondering for once again/stock car, what is the better guess. Did Subaru mess up my intake manifold during the recall ,(and yes it was fine before going 125mph), or is my factory boost solenoid going out at 50,000 miles? And I'm pretty sure the Subaru dealer won't take responsibility for it.
Any ideas let me know
