Had this car come in running rough at idle and Check Engine light on.  It ran good going down the road,  Scanned the car, had codes Po171 lean B1 and P0300 random misfire Opened the hood and removed the engine cover and found the PVC hose had blown off. Reattached the PVC hose and reset the PCM.  Vehicle is fixed.
