Spark plug wire burned up - Smoking Cat?
I was on my way to a shop today (ironically) to get an oil leak which I thought was the pan (what they told me last time I was in) sealed up, because I had tried it twice and was pissed off it was still leaking. The good news is they said the pan isn't leaking, proving I'm somewhat competent. Bad news is, they say it'* the lower intake.
Anyway, on the way there I pulled over because I had smoke coming out from under the hood. After looking under the car, I saw the cat was smoking very badly. So I drove it the rest of the way there, it was only a few minutes out. After doing diagnostics all morning, they told me the plug #5 wire burned up on the exhaust manifold. Very possible, but would this cause a smoking cat?
