Help! All of a sudden my 955 idles super rough. It takes a while to get it up to high rpms also. It sounds ok when it's revved higher but it is severely lacking in power. I replaced the fuel filter and bled everything and it's still kaput. Any ideas? Thanks. I feel like something is seriously amiss when my tractor is sick!

It was running rough, you changed the filter and it still runs rough?

Check amount of fuel flow from tank to inj pump. Is tank venting????? I feel like something is seriously amiss with your profile photo!:thumbdown:

ya I changed the filter thinking that was it and it still runs rough. I just drained the tank and put fresh fuel in it and it still runs rough . What next?

I would try changing my profile pic for starters.

It sounds like you may have a bad injector. Try loosening the line at each injector one at a time while engine is running. On a good injector, the engine should run noticeably rougher or even stall. On the bad injector, you won't notice any difference.
