rys-xt Posted March 22, 2014 Share Posted March 22, 2014 2006 Outback XT 72k Got a cylinder 4 misfire code, car was intermittently idling rough but other than that running good. The spark plugs were replaced within the last several months few thousand miles. No issues since until recently. Took both coil packs off of drivers side, checked with voltmeter, they measured the same. Started the car after resetting the check engine code, car is still idling very rough to the point of stalling. The engine light did not come back on. From an idle, when hitting the gas i could hear a 'pshh' noise that sounded like it was coming from under the inter cooler. After checking the vacuum lines the only hose that looked like it could have issues is the Turbo inlet , which is in rough shape with oil leaking slighty around it. Upon removal, the worm clamp was noticeably loose, the hose is out of round where it mounts to the turbo and seems to be slightly deteriorating but no tears or rips. I'm going to replace and see if that fixes it, but could this cause the issues i was experiencing? Thank you Link to comment Share on other sites More sharing options...
acumenhokie Posted March 23, 2014 Share Posted March 23, 2014 I was going to say yes until you said no tears or rips. If air is getting into the intake flow post MAF it could be the cause of the misfire. Link to comment Share on other sites More sharing options...
