Yes , a failed converter would. Recommend having the CAUSE of the failure diagnosed first before wasting money on a converter and still having problems. Post codes for further advice.
rec. fuel system clean. ethanol treatment to 1 tank premium fuel. ethanol blend in fuel causes build up in fuel system, combustion chambers and exhaust system. this build up can trip sensors.
have codes scanned and post so we can adv, could also be failed o2 sensor
