I was performing routine maintenance on my 08 ranger sport 3.0l, changing the oil & filter, the spark plugs and plug wires, and recharging my K&N air filter.
Before performing any of this maintenance, I disconnected the negative on the battery. Changed out the oil and filter with no issue. Changed the plugs/wires with no issue. Recharged the air filter with no issue. Reconnected the negative. When I fired her back up, I noticed that the ignition was harsh and immediately I went to listen for misfires, which I could hear fairly clearly through the air intake. They were consistently sporatic with no pattern I could notice.
I cut her off, and disconnected the negative again. I pull each plug back out and re-confirmed the gaps. All were on point. I ensured the connections of the wire on both the coil and plugs were tight. Fired her back up and the same deal.
I'll mention I was using Motorcraft platinum plugs and Omni Spark plug wires. I picked up a set of Bosch iridium plugs, pre-gapped (I still checked them and they were spot-on), and Borg Warner plug wires. Rinse and repeat the previous actions and still no change.
At this point, I feel like somehow there is an issue with the ignition coil, even though there was not one prior to this maintenance. Now, I'm starting to step beyond my knowledge and expertise. I would like to know of anyone's opinions before I try replacing the ignition coil OR taking it into the dealership, which I don't really have the money for either. =(
Thank you so much for your help and spending the time to read this.
