my momo has been doing a very strange thing, after 2 or 3 laps my car ingame just stops and wont acelerate again. but if i pump the pedel the bar goes up and down, what can i do to fix this problem.
The fact that the bar goes up and down implies that there is little wrong with you pedals... Are you sure you're not just running out of fuel or something?
Too me, it seems the pedals lose calibration... try replug your wheel, the pedals to the wheel, and even check the contacts inside the pedals... and once you opened it, you moght aswell check and cleanse the potentiometers.
You could also ask either your shop or logitech for a replacement...
Its probably fuel. Goto the pits, and check the "info" section. On the right you will see an initial fuel amount thats put into the car. I'd guess you've got it on 5% - which is very little.
