More G27 problems....HELP!

[-Tephra-]

So whenever I start a race on assetto corsa ill press down the throttle and it will stick for a second it will come off. If I turn my wheel it will do the same, not respond for a second, snap to what the wheel s at, stick there and if I keep turning it wont turn smoothly it will just not respond and snap to that as well. The force feedback worked for the first time ever last night and I cant seem to get it back. I can fix that problem by going into my settings on my G27 profiler, but then I get no force feedback!( which is what a want -_-) If anyone could help that would be great
