I have a momo and it seems like randomly when i respawn first gear works and every other gear seems like it runs partial throttle. Usually if i restart LFS it fixes but somtimes it doest.

Coming out of the pits? You might have the pit speed limiter on - press L.

The XFR, UFR, FZR, FXR, XRR and the single-seaters have limiters, the other cars don't.

Sort of but its random and it still hapens once i exit the pits.

the speed limiter can be turned on at any point of the track, ive got it set as a button on my wheel, right next to the handbrake so sometimes in a fluster i hit the limiter, when it happens next check the dashboard for an orange light, blue is the traction control, yellow is signals and orange is the limiter...i could be wrong on the colour actually but u get the idea, im sure someone on the forum could tell u what colour to actually look for tho

Correction:

Blue is TC

Orange is signals

Red is handbrake

Green is limiter
