I have an issue where after 1/4 throttle my car seems to be struggling to keep the gas flowing. The engine pulsates at about 1/2 throttle. I think ot might be an injector or misfire. Anyone have a similar issue? Car has 170k on it. Anyone have any ideas?

Edit:almost seems like a fuel cut off, if anyone has info please post. You guys are my only hope at the moment

 

Check your codes and see what's going on. I would start with a new fuel filter and go from there.

 

We figured it out, turns out to be bad o2 sensors for bank 1/2, need to get them replaced. Thanks for reply though .
