New Holland TJ 325. Little over 4000 hours. Seems to be something that happened at once, was fine one day then started this. It smooths out when wide open, but at lower rpm’s up to about 1800 it has a bad rattle and vibration and doesn’t seem to have the horsepower it should. Fuel filters have been changed several times and fuel pump pressure checked. Been running it but hate to shake it apart. Any thoughts please?
