Hello everyone,

I thought I share this with you guys. After doing my valve cover gasket and reinstalling everything, I was getting some misfires from Bank 1. After running it through the scanner it would throw cylinder 1,2,3 misfires along with Bank 1 02 sensor.

Will today it was fixed and guess what it was?

It was the 02 sensor connecter, meaning bank 1 sensor was connected to bank 2 and bank 1 connected to bank 2. I swapped them, cleared the code, and NO MORE MISFIRE AND CHECK ENGINE LIGHT.

Good luck and I hope this fix your car.
