The cars gotta get inspected. The check engine lights on. I just had the water pump and timing fixed. I just replaced the sparkplugs, wires, and coil myself. The check engine light is on. I ran it for a couple days , still on. I took off the battery terminal, then ran it for two days. Still on. Had it AEG tested at autozone.. it shows P0301, P0302, and P0440. I believe they are all misfire related. What should I do?

P0301 ans P0302 are misfiing of cylinder 1 and 2 respectively.

Check the spark plugs and related components.

P0440 is a fault with the EVAP system and it could be due to a poorly installed or faulty gas cap. Check that first.
