Q: Cylinder 3 misfires.

asked by on

I have recurring issue with cylinder 3 misfire. And once I had an issue with cylinder 5 misfire. I have changed these plugs numerous times and the problem will come back eventually. I have changed the coil pack as well to be sure. I had the head replaced and many engine part replaced due to it. I have maintained fluid levels so I'm baffled by this problem. Any help would be appreciated. Thanks, Dan

Hi there. From the description you have provided, a lot has been done to overcome your vehicle’s engine misfire issue.

Before you spend more money, attempting to correct the #3 cylinder engine misfire. I recommend having your vehicle’s #3 cylinder engine misfire be diagnosed and repaired by a certified mechanic from YourMechanic.
