2003 MR2 spyder 167000 mile. Runs fine when engine is cold yet misfires and stalls as soon as it reaches normal temperature. P0110 code as well as running to rich and misfire on all cylinders. So far I’ve replaced plugs, engine coolant temperature sensor, and mass air flow sensor. Next step in the repair manual is to check ecu and possibly replace. Looking for ideals. Anyone else have any ideas? Was hoping to use it for the summer but I’m about to just park it in the garage and look at replacing the engine. Any suggestions would be appreciated.
