so my car has had a misfire and i got a p0300 code at first, so i swapped my coils from my driver side( since thats the side the misfire was coming from) to the passenger and then my passenger was misfiring and my driver side was fine. i bought 3 coils and changed them and now im still getting a misfire with a p0303 code which to my understanding thats my 3rd cylinder misfiring. idk if its still a bad coil or bad spark plug. i also changed all my plugs. would love some help. please and thank you.

 

Any luck? It only threw the random miss until you swapped coils? Checked compression yet? I'll look at it if you want to drive down to the bay.

 

I got it all figured out. Just waiting to come across injectors for a good price. My coils were bad as well but now my injector on my 3rd cylinder is shot. But I'm kind of glad it's been sitting cuz I put brembos on, new headlights, and a Nismo lip. So it's a win win situation. Lol
