Tuning ruff and jerking as it goes down the road. The service engine light is on and the etc light stays on. Replaced the Crankshaft sensor in May. The # 3 Cylinder on the diagnostic test from the auto parts store shows that it’s misfiring. I replace the plug in the coil pack already.

So we need to dig a little deeper into the possible causes of the misfire because that will cause your issue.

I attached the detailed test on this code. Let's run through this and see if we can determine the cause.
