my engine was idling really rough but I see my mistake and that was that my ignition connectors were switches thanks to you and first video that shows them how they are plugged in I was able to see that I had them plugged wrong so thanks.
it fixed the misfire? did you have codes? i got p0300 and p0172 (rich condition) changing out sparkplugs, and hopefully that does it. If not getting 6x new coils, and if that doesn't do it 6x new fuel injectors. fml lol
I got the same problem getting to much air in my passenger side valve cover is what the dealership stated need to disassemble to find out what's the problem smh they wanted $1,750 bruhhh I already changed almost everything...
@@lenermaz4546 I changed out the spark plugs and coils still having the same issue. I think its either my passenger side valve cover gasket or my catalytic converter. My o2 sensor readings are good bounce from .1 to .8 volts, but my rear o2 sensor bank 1 bounces from .2 to .4 during idle. It probably will be my valve cover gasket like you said cause I found a bit of oil on sparkplug #5 passenger side by the firewall
@@NouriGains any updates on the situation you were having?? Those are very good things to look out for. I had a misfire on cylinder number 2 so i changed everything including the coil packs.
@@agboyz1624 Changed the spark plugs first, and then changed the coil packs. I had the same issue. It ended up being something with the fuel injectors. I bought two bottles of BG 44K platinum fuel system cleaner (costs like $50 for 2 bottles) I ran 1 bottle on 1/4 tank till empty then another bottle on 1/4 tank till empty. I got over 1,000 miles on the 2003 g35 since, and no check engine lights. Try bg 44k if you are still having the same symptoms after sparkplugs, and coil packs!
