Miata bogging at high rpms PLZ HELP
 

Hello I am a proud owner of a 91 miata and I have having problems with it when I hit about 5k Rpms it starts bogging and full loss of power and starts flashing a check engine light every bog but when I let off the gas it smooths out like nothing happened and the check engine light is gone so I can't check it. But when I try to power over it and just keep pushing it when it's bogging, the bogging will keep happening but at Lower Rpms and will get lower to about 4K. Note: it only happens with a warmed up engine when it's cold there's no problem
