Same code popped up on my 97 Cobra. After going through plugs, wires, coil packs, checking injectors & wiring, it turns out to be due to partial compression loss on cylinder 4's valves (seat, carbon, spring, etc.) My car is sitting until next March/April to check out the head/valves. I had a shop do the diagnosis. The static compression was fine on all cylinders, but a "timed" idle compression test showed #4 built compression more slowly than the neighboring cylinders. See example 3 in the link.

The fog light mod is great, I always hated that they didn't come on without headlights on too. Gotta love the thorough step by step write ups on this site. Your cobra is looking good man

Thanks , I actually just watched a 3 min video on YouTube. Dude had it done in under that so I was like what the hell why not try it. No cutting just pin swap. Had er at local Jack in the box and and competition orange v6 pulled in next to er. Guy and his gal come inside, he asked if she's mine so I'm like yes sir with a smile cause I saw him staring er down while holding pass door so his gal didn't accidently hit my ride. He said my ride was madly beautiful lol. Tried selling me a set of 22s black with red stripe. He had about 10k worth of gold in his mouth. Lol ,really nice guy though.
