Hi there. Among the error codes you’ve listed, a few of them are probably the primary source of your issues. First, the P0300 codes indicate a random misfire. The codes 304, 303 indicate that cylinders 4 and 3 are misfiring. The P0410 OBD-II trouble code is a generic code that the engine control module (ECM) detected the engine O2 sensor did not detect an increase in the O2 level in the exhaust when the air injection system was commanded on during an active test. It’s possible that you have a broken exhaust pipe or exhaust manifold that is causing these codes and the acceleration problems you are experiencing. It is probably a good idea to have a professional mobile mechanic come to your location to complete a car is slow to accelerate inspection, to determine the exact source of your problems and recommend the right repairs.
