Misfire after changing spark plugs cylinder 2
Hey, Scotty I have a question, I have 2005 Scion xa with 120000 miles. I recently changed spark plugs on the car, but when I start up the car in morning, the engine feels like it’s misfiring. But then it goes away. One time I had check engine when I started it up, but now I don’t see that, but I can hear it misfire. What should I do in this case ?
If your plug is gapped and torqued correctly and cylinder 2 still misfires, swap the #2 coil with one of the others and see if the misfire moves to that cylinder. If so, the coil is failing. If not, swap the #2 plug with another cylinder and see if the misfire follows the plug. If so, the plug is bad. Good luck.
What brand of spark plugs did you use? And from what seller?
I have seen multiple videos regarding fake NGK spark plugs, and I suppose there could be counterfeits of other brands as well.
