my diamante was acting up, it would miss fire or leg when i got on the gas but then i found out that it was a sensor on the intake and it drives fine with it off is this bad to drive with it off????????

 

i, guess its bad to drive around w/ out your sensor, for the reason your pcu is getting confuse. those sensor also tells the pcu when to open the throttle plate .and whats goin on now is, you manually controlling the air intakes / throttle.
