Can i drive for a little time with bad sensors?

Ive got an 03 i35 with like 120,000 miles. Last
week it was dying and I had to change out a
camshaft position sensor and that seemed to
work, no more problems starting and no more
dying while running. The next day it starts to
run kinda bad while driving and knocking a
little. I was sure it had oil but i added a little
anyway just to try something but no such
luck. So I checked codes again and now it's
throwing a crankshaft position sensor and
also the throttle body sensor and is always
running rough. Problem is ive got to drive it to
work and back, about an hour drive, for at
least a week before I'll have more money to
work with. Im worried its gonna really mess
up on the way to or from work and then the
whole thing might be a lost cause. Any help
will be appreciated. Ive been told I could try to
clean the throttle body really well and that
would help. Is there maybe an inexpensive
way to keep going without causing further
damage until ive got the money for these
parts? And im thinking that even after i get
these parts that by then i will have damaged
another area. Thank you for reading and if
youve got any advice id love to hear all of it.
