My car's engine is misfiring I get codes P0302 and P0300 usually at the same time. Really rough idle where it vibrates in the cab.
I changed spark plugs and spark plug wires and the airflow sensor and it ran better for a while where it would only give check engine once a week. Now it's every single day at least once it triggers check engine light, usually when accelerating. I took it to a shop and they couldn't find the problem but said the fuel pressure is okay and told me maybe its the fuel injectors not working properly.
What should I do?
