Firstly, make sure to check your spark plugs and ignition coils for any wear and tear. They may need to be replaced to improve engine performance. Additionally, consider using a fuel additive to clean any carbon build-up in the engine.

Another common cause of this issue is a dirty air filter. Make sure to clean or replace it as necessary. Also, check your battery and make sure it is fully charged. A weak battery can affect engine starting in cold temperatures.

It's possible that the problem lies in the fuel injectors. You may need to have them professionally cleaned or replaced. Also, check for any vacuum leaks as they can cause misfires. These can be detected with a smoke test.
