Good afternoon.

What are the engine codes?

How old are the tune up parts?

Code said o2 sensor but both was replaced. Upper and lower. Still do not have any go power. Code only said o2 sensor and multiple misfires. Tune up along with coil pack recently.

Can I have the numbers?

Codes never identify bad parts just failed systems. Once I know the numbers, I can get you specific ideas of what the PCM sees.
