My wife got a flashing engine warning lamp last night, and pulled over and called me (bless her!). After shutting down and restarting, the lamp was solid. So I told her to come home gently as long as it's solid.
When I got home, my ScanGaugeII pulled a code "P0302", misfire on cylinder #2 (after searching online and here). I cleared the code, and went around the block. Felt rough, and by the time I got home, P0302 was back.
This morning, cleared the code, and swapped coils #2 and #3. Took it for a spin, and unfortunately, the code is still P0302. So it does not appear to be the coil.
We purchased this '06 Mounty V8 in August with 74,000 miles, and now has ~82,500. The previous owner said he's put 8 new Champion Double-Platinum #7989 at some point (I have a note out to him for the mileage). He said he managed to not break any of them, and put the recommended lube on the new ones.
I'd rather not touch the plugs until I've exhausted all other cheap/easy options. Anything else I should check before I pull plug #2?
Also, I have no proof that the plugs were changed, although I have no reason to believe otherwise. But what would the markings/branding be on the plugs, if these turn out to be the originals. Of course, if that's the case I'm due for all 8 plugs to be changed.
