Having issues fellas...I was entering on to the highway..so I accelerated. .and as soon as I hit 5k rpms...CEL started blinking and when I let off the gas and try to cruise ...the car had that shakes until I pulled over to turn off the car and turn her back on and the shakes went away and I can cruise fine but now everytime I push it to 5k I get the same issues and I hear a rattle under the car...I replaced all plugs and coil packs and before I start throwing parts I kinda need some direction or opinions. .....I ran codes and I got cylinder 3 misfire and catalytic threshold on that same bank.... 02 sensor ?...crankshaft sensor..camshaft sensor...fuel pump??..freeze data showed both fuel system 1 and 2 with a open loop fault..meh...any help would be great
