I have a 2001 new holland 545d with turbo, that is very slow to rev up, it idles fine, and starts fine, but when the throttle is applied it takes about 15-20 seconds to reach 1100 rpms and will not exceed that, and i am not sure but i think it should reach 2600 rpms in about 3 seconds, I put a new fuel filter on but I am not sure that it was the right one, it was actually bought for a bulldozer but it fit so I tried it, and it did seem to help a little, but there is still a problem, any help would be appreciated. thanks
