i have a 2015 AWD sportage which after we fixed the B camshaft timing error, U1111 appears on the scanner and mechanic is having a hard time fixing it. even the idling is still rough , brake is hard as no vacuum after the replacement of the camshaft phaser on both intake and exhaust. What could still be the possible issue of the rough idling with stiff brake pedal and the U1111 error code that keeps on appearing after the ECU reset. Could somebody help me on this? Thanks
