started my 2002 mustang GT as usual and felt a little rough and felt bumping coming from the dash. The exhaust note wasn't the same. It was like little explosions going out the exhaust tips. When driving it, it felt like it was having trouble gaining speed. At the light it would shake and feel rough. I pulled over at a gas station and retuned it.. Didn't work. I drive on the highway and at high speed it felt better but still a bit rough. I went back into the streets and the check engine started flashing. I pulled over again and checked the codes with my Bama tuner. It gave me P0301 and P0316. I clicked on both and only P0301 had a description : cylinder 1 misfire.
I popped the hood while the car Was on and removed plug by plug. Each plug made that bump.bump.bump noise when I removed each one so what can it be??
