Does anyone know why P0300, P0301, and P0306 would pop up? I went to run some errands this morning and my Check Engine light came on, it was solid for about a minute then flashed several times and then remained solid for the rest of the time. It came on after the next three starts and remained solid but after the fourth start of the day it went off and hasn't come back on. I checked it with my OBD-II reader when I got home and that is what gave me these codes. About two weeks ago I had the fuel module and all six injectors changed out and everything has been running fine. It does not seem to be running any differently. Does anyone know what might be causing this???
