Thread: need some advise for spark plugs

like a misfire?

Yeah i guess idk i have never had this problem before with any car, but my scanner is saying it's a random cylinder missfire. It started when i was on the highway and i steped on it and when i got up too 112mph the ses light flashed on and it lost performance, it idled fine then and it still idles and starts up fine now, its just when i give it the gas it boggs down i have no performance.
