hardus77 Posted May 16, 2019 Share Posted May 16, 2019 Hello everyone, So I was driving minding my own business and then the CEL started flashing. I managed to find a parking lot where I plugged in my ECU reader. P0303 Cylinder #3 misfire. So I buy a new set of plugs gap them perfectly and installed them along with a new Coil for Cylinder #3. I cleared the codes and it didn’t fix the problem. My friend says it could be Injector? I’ve also been told it could be PCV being stuck. Please enlighten me with your insightful and hopefully accurate and backed up information. Thank you all for chiming in!https://192168ll.onl/https://xender.vip/ https://testmyspeed.onl/ Thank you!

whitetiger Posted May 16, 2019 Share Posted May 16, 2019 to rule out the injector, swap it with another cylinder and see if the misfire code moves with the injector. aside from that, you could have piston or valve issues as well. a leak-down and compression test is in order for you.

cww516 Posted May 17, 2019 Share Posted May 17, 2019 Moved to the 4th-gen forum- you'll probably get more traffic and more advice in here. whitetiger is pretty much spot-on, though. Welcome to the forum! Link to comment Share on other sites More sharing options...
StkmltS Posted May 21, 2019 Share Posted May 21, 2019 Yep, swap the injector to another cylinder and pray the misfire moves with the injector. Good luck. My DiySB rebuild Got Misfires? Link to comment Share on other sites More sharing options...
gkinslow Posted May 21, 2019 Share Posted May 21, 2019 Make sure the coil pack connector is unbroken and seated properly as well. Link to comment Share on other sites More sharing options...
