Have 5.4 engine that has had regular mobil 1 5/20 oil changes with a motorcraft filter,truck runs fine with a rough idol at times,lately when truck sits overnight it seems to rev higher for first couple seconds with a lot of engine noise till oil pressure gauge starts to move and then quiets down to normal, not sure if its related but air bag light comes on once in a while when driving.. Thanks
