Hello , I’ve recently been experiencing two different symptoms on my xterra. About a month ago my car misfired on the second cylinder (P0302) by lagging to accelerate when I pushed the pedal and then it would go after a second. I assumed it was a coil or spark plug so moved the coil on the second cylinder to the fourth cylinder and erased the codes to see if the coil misfire would move. Unfortunately a whole month went by and I got no misfire at all! Then a few days ago I got a random misfire (P0300) and the car was shaking , while my check engine light was blinking. I want to mention I was experiencing this random misfire while I was on my reserve gas and my orange emergency gas light was on. I then filled up my whole tank and have not had a misfire since I filled up my tank 5 days ago. Do you guys think this might be fuel related ? Any one else experience the same thing ?
