2011 Landau Atlantis 250 with 2010 mercury optimax 200 pro xs
Had problem with cap on oil reservoir mounted on engine came loose which caused oil to pump out, horn went off and put air in system and now has a miss when in gear going low rpms. Bled system out but after that it will not allow to go over 4000 rpms. Comes out of the hole great with no miss. Now horn goes off every 2 minutes and flashes engine and oil symbol. Any ideas what the problem could be please?
