Does my car need a tune up?

Question

I have a 2007 chevy impala. My car shakes all the time and when I press on the gas it shakes even more then it will stop. I took it to multiple shops and they all said something different. The code is p0305

Answer 1

HI there

P0305 indicates a cylinder misfire on cylinder 5. This can be the result of a bad spark plug or ignition coil. However the other code points to more of a problem with the fuel injector on that cylinder. Here some good info on the second code P1174
