Hello, so I have 2010 Toyota Prius, it recently had the catalytic converter stolen so I had to replace it and also the O2 sensor. After this tho the car began sputtering and check engine came on. When the code was scan it said ignition misfire, so I had my ignition coils and spark plugs changed. But the sputtering has continued by the engine light is off. I have then put fuel system cleaner but after a day of driving the sputtering continues. Also the coolant seems to be burning as well but could the reason for the coolant be the reason for the misfire. And also should I continue refilling the coolant? if there is anyone who could help I will greatly appreciate it or if anyone know a mechanic that specializes in hybrids in the Chicagoland area so I can get the car check that would be great also.

Yes, it definitely can.
And also should I continue refilling the coolant?
You should not let the car suffer from overheating. How many miles on the car? Take the car to a good mechanic to see what the issue is and decide accordingly.
It has a little over 220,000 miles and thank you for the help.
You're welcome. Keep us posted.
If coolant is disappearing, it could be a blown head gasket. The third generation Prius is known for blown head gaskets.
