At first my Catalytic converters were making a loud sound reading Codes 0171 and 0174. Brought it in to the dealer and they replaced fuel filter. Then I said what about the Catalytic Converters being bad. So then they replaced those. Then I picked it up and the Engine light is still on reading code of P0300 and chugging until it warms up. Said I need my fuel injectors cleaned. I did that 2 times and replaced plugs and wires and engine light is still on and now when I just turn the key to accessories without actually turning it over it makes like a winding sound for about 30 seconds.
