P0300 please help
Hello everyone , yesterday I took my G out and when I was waiting at the light to turn green the car all of a sudden started idling rough, light turn green so I started going and it felt really bad, as i was pulling over I smelled a cent of burned wires and bad fuel, I got to a near advanced auto parts ran the codes because SES light was flashing, I got P0300 and P0305 i changed my spark plugs to denso iridiums that's what I was running previously, didn't work, I changed coil #5 car somewhat felt a little better but still running bad I took it to advanced again because is down the street from me and I got code P0302 I changed coil #2 and finally It was working perfect ! But 2 minutes later it got worse again SES light was flashing again, nd it smoked from coil #3 it smelled like burned wires but I don't see any burned wires ! Now I only have codeP0300 and is running like complete **** it has barely any power what can it be ?!?!? Please help

I just re-read and realized how much you might have screwed yourself. Have you changed plugs before? Do you know how tight to go with them and about the crush washer etc?
When you get a misfire start with swapping that coil with another and resetting the ECU by pulling the battery cable or the other way if you are familiar/confident with it. That way you know if it is the coil or something you messed up like a loose connector.
Smoke from cylinder 3? Like white smoke coming out of the spark plug tube when you pulled it? Or when it is running?
