My car just started misfiring out of no where. I wasnt stressing the engine hard i had just got done going up a mountain, i keep my engine health as top priority. i pulled over turned it off checked the codes and said it was misfiring, the device i checked the codes with is also what i tune it with the diablo handheld tuner. I pressed restore backup thinking it was the tune, well i started it back up and it still misfired so i immediately made the trip back home. Going down the mountain it stopped for a bit, i kept the car in 2nd gear going down the mountain and sent it a couple times. After i got down the mountain it stopped and hasnt done it since.

but i think i know what it is below is a picture of the code it gave and what i think is causing the mess the second pic is one of the cords melting to the headers which a shop did and dont worry they are going to fix it... any help is greatly appreciated



UPDATE: found this hose i remember the shop saying they had to unplug for it to run. in the video file at the very bottom

Well, the melty sh*t on the exhaust would give me pause. I'd start there as that it obvious and screams "look at me!"
