is it cause o2 sensors

[ajonesz28]

i used a scanner on my camaro it said the o2 sensors are bad will this effect my cars acceleration or can there be another problem i changed the fuel filter it accelerates a little better but i havent checked the pressure but before i put the filter on it the fuel pressure was only at 20psi

Which ones are bad? You need the front but the rear can be tuned out. Bad o2's will effect the engines performance. Good Luck

What were the codes? Might not be the sensors at all if the fuel pressure was that low, maybe P0171 and P0174? Recheck the fuel pressure it should be about 58 psi.
