While on the interstate today a CEL came on, i went to the local auto shop so they could read the warning with their OBD diagnostic test. It says the Cylinder 3 is misfiring. I replaced all 6 of my spark plugs about 3 weeks ago, so if that has anything to do with it please let me know. I told the guy who checked the CEL warming i changed my spark plugs a little shy of a month ago and he just said that its more than likely a grounding problem...or a coil problem...is he semi correct ? What could it be ? I am a college student so the most reasonable $$$ answer would be best. Btw if it helps, my car has approx 165,000 miles on it.

Check all the connectors and make sure the spark plug wires are pressed into the spark plug holes.

Could be coil on that cylinder or injector. Which spark plugs they used on your car? These cars require oem quality-NGK brand.

I am not sure which spark plugs i installed honestly. Some type of two pronged irridium ? Anyways...i know they were not that "NGK" brand :/ damn. Before i change/replace spark plugs i am going to just double check the tightness of bank 3's spark plug first and make sure i have the connector on tightly. Thanks ! I will let you all know how it goes tomorrow.
