hi, i have a 2000 chevy k3500 just bought a couple of months ago and its misfiring now it has po174 trouble code, its not that bad but when i get up to the second third and i think fourth gear it becomes really sluggish and the ticking gets louder. i have replaced the plugs, wires, cap, rotor, coil, crank shaft positioning sensor, ecm, and now i'm thinking of trying to see if its the fuel pressure regulator... i don't know where that is at on my truck so if you could point in the right direction that would be great but if you think it might be something else i definitely would like the help/opinions thanks
