I have a Kia Rio5 08’, my engine light says my problem is error P0302. I changed my spark plugs a year and a half ago and my ignition coil like 3 years ago. I haven’t changed the fuel filter but I think that might be the problem. I also get error P0456. I’m thinking about just changing the fuel filter. Anyone know where to find it o have any advice on what the problem might be?
My car sometimes hesitates when accelerating.

I'd start with this:

• use injector cleaner and good gas, check gas cap
• switch coils and spark plugs between cylinders 2 and 3 and see if error code changes to P0303 - then you know it's either plug or coil
• switch injectors between 2 and 3
• look for vacuum leaks
